Doctoral Degree in Computer Science

Carnegie Mellon's Ph.D. in Computer Science is, above all, a research degree. When the faculty award a Ph.D., they certify that the student has a broad foundation and awareness of core concepts in computer science, has advanced the field by performing significant original research and has reported that work in a scholarly fashion.

When you begin our Ph.D. program, you’ll take the Introductory Course for Doctoral Students — an intense two week program that orients you to the department, introduces you to research and education topics our faculty are interested in, helps you find a faculty advisor and familiarizes you with Carnegie Mellon’s resources. Next, you’ll gain a broad understanding of fundamental research issues in major areas of computer science through coursework and original research. Finally, you’ll write and orally defend a thesis that guarantees you understand the area well enough to advance the state of knowledge in the field.

During the first two years of the program, you’ll gain the foundation of knowledge that will allow you to become an expert researcher in computer science, primarily by

Mastering a body of graduate material, achieved by passing 96 university units worth of graduate courses (equivalent to eight full-time courses).

Learning how to organize and begin to carry out original research, achieved by participating in directed research.

You will also serve as a teaching assistant, hone your writing and speaking skills and maintain your programming prowess. You’ll also receive periodic evaluation of your progress, and must make satisfactory progress to continue in the program.

Time Commitment:

As a Ph.D. student in computer science at CMU, you'll spend roughly five years acquiring a body of technical knowledge that includes a familiarity with the breadth of the field, as well as a deep understanding of your research area. From your second month in the program, you'll work closely with your faculty advisor, who is charged with guiding your education and monitoring your progress through the program. You'll take courses, teach and perform directed research — all to ensure that you leave Carnegie Mellon as an expert in your field. For a complete breakdown of our program requirements, read our Ph.D. Handbook .

Financial Information:

The Computer Science Department offers all Ph.D. students full financial support while they are in good academic standing in their respective programs. To learn more about Ph.D. funding, visit the SCS  Doctoral Programs  webpage.

Computer Science Ph.D. Program

You are here.

The Cornell Ph.D. program in computer science is consistently ranked among the top six departments in the country, with world-class research covering all of computer science. Our computer science program is distinguished by the excellence of the faculty, by a long tradition of pioneering research, and by the breadth of its Ph.D. program. Faculty and Ph.D. students are located both in Ithaca and in New York City at the Cornell Tech campus . The Field of Computer Science also includes faculty members from other departments (Electrical Engineering, Information Science, Applied Math, Mathematics, Operations Research and Industrial Engineering, Mechanical and Aerospace Engineering, Computational Biology, and Architecture) who can supervise a student's Ph.D. thesis research in computer science.

Over the past years we've increased our strength in areas such as artificial intelligence, computer graphics, systems, security, machine learning, and digital libraries, while maintaining our depth in traditional areas such as theory, programming languages and scientific computing.  You can find out more about our research here . 

The department provides an exceptionally open and friendly atmosphere that encourages the sharing of ideas across all areas. 

Cornell is located in the heart of the Finger Lakes region. This beautiful area provides many opportunities for recreational activities such as sailing, windsurfing, canoeing, kayaking, both downhill and cross-country skiing, ice skating, rock climbing, hiking, camping, and brewery/cider/wine-tasting. In fact, Cornell offers courses in all of these activities.

The Cornell Tech campus in New York City is located on Roosevelt Island.  Cornell Tech  is a graduate school conceived and implemented expressly to integrate the study of technology with business, law, and design. There are now over a half-dozen masters programs on offer as well as doctoral studies.

FAQ with more information about the two campuses .

Ph.D. Program Structure

Each year, about 30-40 new Ph.D. students join the department. During the first two semesters, students become familiar with the faculty members and their areas of research by taking graduate courses, attending research seminars, and participating in research projects. By the end of the first year, each student selects a specific area and forms a committee based on the student's research interests. This “Special Committee” of three or more faculty members will guide the student through to a Ph.D. dissertation. Ph.D. students that decide to work with a faculty member based at Cornell Tech typically move to New York City after a year in Ithaca.

The Field believes that certain areas are so fundamental to Computer Science that all students should be competent in them. Ph.D. candidates are expected to demonstrate competency in four areas of computer science at the high undergraduate level: theory, programming languages, systems, and artificial intelligence.

Each student then focuses on a specific topic of research and begins a preliminary investigation of that topic. The initial results are presented during a comprehensive oral evaluation, which is administered by the members of the student's Special Committee. The objective of this examination, usually taken in the third year, is to evaluate a student's ability to undertake original research at the Ph.D. level.

The final oral examination, a public defense of the dissertation, is taken before the Special Committee.

To encourage students to explore areas other than Computer Science, the department requires that students complete an outside minor. Cornell offers almost 90 fields from which a minor can be chosen. Some students elect to minor in related fields such as Applied Mathematics, Information Science, Electrical Engineering, or Operations Research. Others use this opportunity to pursue interests as diverse as Music, Theater, Psychology, Women's Studies, Philosophy, and Finance.

The computer science Ph.D. program complies with the requirements of the Cornell Graduate School , which include requirements on residency, minimum grades, examinations, and dissertation.

The Department also administers a very small 2-year Master of Science program (with thesis). Students in this program serve as teaching assistants and receive full tuition plus a stipend for their services.

• Where To Earn A Ph.D. In Computer Science Online

Where To Earn A Ph.D. In Computer Science Online In 2024

Published: Mar 27, 2024, 3:00pm

As our reliance on technology grows, so does our need for advanced computer professionals and educators. Despite the number of conferred graduate degrees in computer and information sciences nearly tripling between the 2010–11 and 2020–21 academic years, tech fields are facing a widening skills gap.

While many schools nationwide have developed computer science doctoral programs to help meet professional demand, online Ph.D. in computer science programs are still quite rare. Most schools only offer in-person programs, meaning students who need to work while they study have limited options.

In this guide, we showcase the two online doctorates in computer science that met our ranking criteria. We also explore factors you should consider when choosing a program.

Consider Your Future Goals

Your postgraduate goals should play a central role in your school and program decisions. Knowing what type of career and specialization you want can help you choose the right online doctorate in computer science.

For example, you might enroll in a research-based program if you plan on teaching, while a practice-based program may suit you if you aspire to take on an advanced computer science role .

You can also compare how well each school and program supports your plans. Check each degree’s curriculum, faculty, and mentorship and partnership opportunities to identify how it can help you meet your long-term goals.

Understand Your Expenses and Financing Options

The high cost of a graduate degree can make postsecondary education seem out of reach for many. Total tuition for the programs on this list costs $57,000 at Capital Tech and around $59,000 at NU—that’s a hefty financial investment.

However, you may have financial aid available to you. By completing the Free Application for Federal Student Aid (FAFSA®), you can qualify for various federal grants, scholarships and work-study programs. Other aid providers may use FAFSA data to determine their awards as well. Some schools, including Capitol Tech, also offer tuition discounts to veterans and active service members.

For many students, online degrees make graduate school more accessible thanks to flexible scheduling and reduced travel demands. But the online learning experience differs from on-campus programs, and earning a Ph.D. in computer science online might not work for everyone.

Both online programs on this page feature asynchronous courses, allowing you to study on your own time. However, this also requires more independence, time management and organization. You might also find the environment to be less structured and interactive.

If you thrive in a more traditional classroom experience, synchronous online classes or a hybrid program might fit your needs better.

Accreditation ensures your school or program has undergone a rigorous evaluation process. Your university’s institutional accreditation status can affect your eligibility for financial aid, transfer credits, professional credentials and employment.

Check that your college is accredited by an organization approved by the U.S. Department of Education or the Council for Higher Education Accreditation (CHEA). You can confirm any school’s accreditation status through CHEA’s directories .

Programmatic accreditation provides quality assurance for specific degree programs and departments within universities. ABET accredits computer science degrees , but it does not provide accreditation for doctoral programs.

Our Methodology

We ranked two accredited, nonprofit colleges offering online computer science Ph.D. programs in the U.S. using 14 data points in the categories of student experience, credibility, student outcomes and affordability. We pulled data for these categories from reliable resources such as the Integrated Postsecondary Education Data System ; private, third-party data sources; and individual school and program websites.

Data is accurate as of February 2024. Note that because online doctorates are relatively uncommon, fewer schools meet our ranking standards at the doctoral level.

We scored schools based on the following metrics:

Student Experience:

• Student-to-faculty ratio
• Socioeconomic diversity
• Availability of online coursework
• Total number of graduate assistants
• Portion of graduate students enrolled in at least some distance education

Credibility:

• Fully accredited
• Programmatic accreditation status
• Nonprofit status

Student Outcomes:

• Overall graduation rate
• Median earnings 10 years after graduation

Affordability:

• In-state graduate student tuition and fees
• Alternative tuition plans offered
• Median federal student loan debt
• Student loan default rate

We listed the two schools in the U.S. that met our ranking criteria.

Can I get a Ph.D. in computer science online?

Several schools offer a fully remote or hybrid Ph.D. in computer science. Online degrees typically feature the same content as their in-person counterparts and award the same academic credentials; in many cases, they differ only in delivery format.

Can you get a Ph.D. virtually?

Yes, fully online Ph.D.s in computer science allow you to complete your coursework, perform research, watch seminars and attend meetings virtually. However, your program may feature fieldwork requirements that must be completed in person.

Is it worth getting a Ph.D. in computer science?

A Ph.D. in computer science can prove beneficial for many people, including those who want to work in a postsecondary teaching or research position. Doctorates in computer science can also help professionals advance their careers and take on influential positions in the industry.

How long is a Ph.D. in CS?

The length of your Ph.D. in computer science depends on the program, your previous education and your course load. The programs on this list take about three years to complete, but many others take four to five years.

For nearly a decade, Doug Wintemute has specialized in helping students and professionals make sound education and career decisions. In addition to Forbes Advisor, his work has been featured on many online publications, including ZDNet, Bankrate and NurseJournal.

Doctoral Program

The primary focus of the doctoral program is research, with the philosophy that students learn best by doing—beginning as apprentices and becoming junior colleagues working with faculty on scholarly research projects. The faculty in the department conduct research in all areas of computer science. The doctoral degree requires a dissertation based on the candidate’s original research, which is supervised by a faculty member, and all students in the doctioral program are actively engaged in research throughout the program.

The PhD is the Computer Science Department’s primary doctoral program.  PhD students are expected to be full-time on-campus during every fall and spring academic semester from initial enrollment until the dissertation has been distributed to their defense committee, except during leaves of absence approved by the university.  PhD students spend at least half of their time on research under the direction of their faculty adviser from their first day in the program and devote themselves full time to research after coursework and other preliminaries have been completed. PhD students are also expected to participate in departmental and laboratory activities full time throughout the program, except possibly for summer internships elsewhere, and the department does not consider admission of part-time PhD students.

Press mentions, dean boyce's statement on amicus brief filed by president bollinger.

President Bollinger announced that Columbia University along with many other academic institutions (sixteen, including all Ivy League universities) filed an amicus brief in the U.S. District Court for the Eastern District of New York challenging the Executive Order regarding immigrants from seven designated countries and refugees. Among other things, the brief asserts that “safety and security concerns can be addressed in a manner that is consistent with the values America has always stood for, including the free flow of ideas and people across borders and the welcoming of immigrants to our universities.”

This recent action provides a moment for us to collectively reflect on our community within Columbia Engineering and the importance of our commitment to maintaining an open and welcoming community for all students, faculty, researchers and administrative staff. As a School of Engineering and Applied Science, we are fortunate to attract students and faculty from diverse backgrounds, from across the country, and from around the world. It is a great benefit to be able to gather engineers and scientists of so many different perspectives and talents – all with a commitment to learning, a focus on pushing the frontiers of knowledge and discovery, and with a passion for translating our work to impact humanity.

I am proud of our community, and wish to take this opportunity to reinforce our collective commitment to maintaining an open and collegial environment. We are fortunate to have the privilege to learn from one another, and to study, work, and live together in such a dynamic and vibrant place as Columbia.

• Additional forms and resources from SEAS

PhD Course Guidelines:

PhD students must work with their advisors to develop a program of study that meets the following requirements.

• For direct Ph.D. degree students: 54 credit hours (minimum of 42 credit hours of course work available for graduate credit and minimum of 12 credit hours of dissertation research credits (CSCI 8999)) are required. Additionally, a student should continue to enroll in Continuing Research - Doctoral (SEAS 0940) until their dissertation is completed.
• For post-Master’s Ph.D. students: 18 credit hours of course work available for graduate credit and 12 credit hours of dissertation research credits (CSCI 8999) are required. Additionally, a student should continue to enroll in Continuing Research - Doctoral  (SEAS 0940) until their dissertation is completed. 
• A maximum of 15 credits outside of the department for direct Ph.D. students; a maximum of 9 credits outside of the department for post-Master’s Ph.D. students.
• Algorithms and theory;
• Software and systems
• See details in the Preliminary Examination section below. 

Preliminary Examination

Failure of full-time students to pass the preliminary examination by the end of the fourth semester will lead to dismissal from the program.

Students who register for 6 credits or fewer in three consecutive semesters are part-time. Part-time students are required to pass the preliminary examination within their first three years, or 30 credits, of enrollment in the PhD program. Failure to do so will result in dismissal from the program.

To demonstrate competency, students may take one course in each of the following areas:

• Algorithms and theory: CSCI 6212 Design and Analysis of Algorithms or CSCI 6311 Theory of Computation
• Software and systems: CSCI 6221 Advanced Software Paradigms, or CSCI 6431 Computer Networks, or CSCI 6461 Computer System Architecture

Competency is demonstrated in one of two ways:

• By completing the course with a minimum grade of A-; or,
• By taking only the written, in-class examinations in the course. With this option, students must pass all exams given during a semester, earning a minimum grade of A- in each. 

Students who prove, via their official transcript, that they earned the requisite grades as part of their master’s degree may apply that result to the preliminary exam requirement. 

Students must submit a Preliminary Examination Form to the Department of Computer Science after completing the requirements for the preliminary exam. 

Publication Requirements

Students must have at least one peer-reviewed conference or journal paper accepted for publication at the time of the dissertation defense.

As a guideline, students are expected to have at least two or three conference or journal papers accepted for publication by the time of their dissertation defense, and the material from those papers should be the core of the dissertation.

Dissertation

Dissertation advisor and co-advisor(s).

Every PhD dissertation must be supervised by a faculty advisor who must be (1) a regular full-time faculty member of GW with a primary or secondary appointment in the CS Department, or (2) a research faculty member of the CS Department. Besides the dissertation advisor, a PhD student may have one or more co-advisor(s), who may be full-time or part-time faculty at GW, or professionals from outside the university. Co-advisors are expected to hold a terminal degree.

Forming a dissertation committee

• The dissertation committee must consist of at least three members, including the major advisor. Additional advisor(s) and co-advisors are optional and additional to the three members.
• The committee must have a presiding chair who is a regular full-time faculty member whose primary appointment is in the Department of Computer Science. The committee chair may not be the student's research advisor or co-advisor.
• Faculty with secondary appointments in the Department of Computer Science are not considered regular full-time faculty members in the Department.
• At least one member of the committee must be an external reviewer. The external reviewer must hold a doctoral degree. They may not be a research advisor or co-advisor of the student. They should have a primary appointment in another GW department or outside the University.
• The dissertation committee must be approved by the Chair of the Department of Computer Science.
• The committee membership is normally the same for the dissertation proposal examination and the dissertation defense. However, the membership may change with the approval of the advisor and department chair.

Dissertation proposal defense

• The defense may not take place before the student has passed the preliminary examination.
• The student’s advisor must approve the scheduling of the dissertation proposal defense.
• The student submits a written proposal, in the style of a dissertation, to the members of the dissertation committee. The proposal should contain preliminary results.
• The dissertation committee evaluates the proposal and conduct an oral examination of the student. The committee conveys its recommendation of pass/fail to the Department of Computer Science.
• A proposal defense report should be filed.  

Dissertation defense

• The dissertation defense may not be scheduled before the student has passed the dissertation proposal defense.
• The student’s advisor must approve the scheduling of the dissertation defense.
• The student submits a written dissertation to the members of the dissertation committee, normally two or more weeks in advance of the defense. The writing should follow the dissertation writing guidelines .
• The committee evaluates the dissertation and conducts an oral examination of the student. The committee conveys its recommendation to pass or fail to the Department of Computer Science.
• The final examination approval form and the dissertation completion form should be filed.

University Graduation and Scholarship Requirements

Students are responsible for knowing the University’s graduation and scholarships requirements. Consult the University Regulations section of this Bulletin. Students should consult the department for additional information and requirements.

Secondary Menu

Phd program, find your passion for research.

Duke Computer Science gives incoming students an opportunity to investigate a range of topics, research problems, and research groups before committing to an advisor in the first year. Funding from the department and Duke makes it possible to attend group meetings, seminars, classes and colloquia. Students may work on multiple problems simultaneously while finding the topic that will motivate them through their first project. Sharing this time of learning and investigation with others in the cohort helps create lasting collaborators and friends.

Write a research proposal the first year and finish the research the second under the supervision of the chosen advisor and committee; present the research results to the committee and peers. Many students turn their RIP work into a conference paper and travel to present it.

Course work requirements are written to support the department's research philosophy. Pass up to four of the required six courses in the first two years to give time and space for immersing oneself in the chosen area.

Years three through five continue as the students go deeper and deeper into a research area and their intellectual community broadens to include collaborators from around the world. Starting in year three, the advisor funds the student's work, usually through research grants. The Preliminary exam that year is the opportunity for the student to present their research to date, to share work done by others on the topic, and to get feedback and direction for the Ph.D. from the committee, other faculty, and peers.

Most Ph.D students defend in years five and six. While Duke and the department guarantee funding through the fifth year, advisors and the department work with students to continue support for work that takes longer.

Teaching is a vital part of the Ph.D. experience. Students are required to TA for two semesters, although faculty are ready to work with students who want more involvement. The Graduate School's Certificate in College Teaching offers coursework, peer review, and evaluation of a teaching portfolio for those who want to teach. In addition, the Department awards a Certificates of Distinction in Teaching for graduating PhD students who have demonstrated excellence in and commitment to teaching and mentoring.

MIT Doctoral Programs in Computational Science and Engineering

The Center for Computational Science and Engineering (CCSE) offers two doctoral programs in computational science and engineering (CSE) – one leading to a standalone PhD degree in CSE offered entirely by CCSE (CSE PhD) and the other leading to an interdisciplinary PhD degree offered jointly with participating departments in the School of Engineering and the School of Science (Dept-CSE PhD).

While both programs enable students to specialize at the doctoral level in a computation-related field via focused coursework and a thesis, they differ in essential ways. The standalone CSE PhD program is intended for students who intend to pursue research in cross-cutting methodological aspects of computational science. The resulting doctoral degree in Computational Science and Engineering is awarded by CCSE via the the Schwarzman College of Computing. In contrast, the interdisciplinary CSE PhD program is intended for students who are interested in computation in the context of a specific engineering or science discipline. For this reason, this degree is offered jointly with participating departments across the Institute; the interdisciplinary degree is awarded in a specially crafted thesis field that recognizes the student’s specialization in computation within the chosen engineering or science discipline.

For more information about CCSE’s doctoral programs, please explore the links on the left. Information about our application and admission process is available via the ‘ Admissions ‘ tab in our menu. MIT Registrar’s Office provides graduate tuition and fee rates as set by the MIT Corporation and the Graduate Admissions section of MIT’s Office of Graduate Education (OGE) website contains additional information about costs of attendance and funding .

Why enroll in a PhD?

What’s a phd degree, and why should one get one.

A PhD, or a Doctor of Philosophy Degree, is the highest degree that one can earn in the United States. An essential component of the Ph degree is performing original research, i.e., creating new knowledge, a body of knowledge that was not available before. This essentially means that as part of doing a PhD, you are solving a non-trivial problem, for which no solution was previously known. Through a PhD degree, you get training in doing research. You also acquire a lot of advanced knowledge in the subject area you choose, and you become the world’s leading expert in that area.

If you are gifted, creative, think outside of the box, and are passionate about computing, you should definitely pursue a PhD. A PhD degree in computer science is highly valued in industry, academia, as well as industrial and government research labs. As a leading expert in the subject area, academia and industrial/government labs will be interested in you and would want to hire you. The computing industry will hire you because you have gone through the training of solving really hard problems in a creative manner, and the companies want to use this skill that you have learned while doing your PhD for solving other issues that they may have, even those that are not related to your subject area. A PhD degree holder gets a lot of respect in the general community as well. Big tech companies would want to hire you as a part of the team engaged in developing future technologies. Above all, earning a PhD can give you the satisfaction of doing something that no one had done before: solving a problem that was unsolved until you solved it.

Doctoral research has been important for humankind’s progress. Many significant and vital discoveries were made as part of an inventor’s PhD thesis. For example, the automatic theorem-proving procedure that underlies nearly all AI reasoning systems was discovered by Jacques Herbrand as part of his PhD thesis research.

It all sounds pretty hard, would I be able to do it. How would one be able to solve a problem that no one else could solve earlier?

It is certainly not easy to earn a PhD. A PhD degree requires a large amount of dedication, passion, and hard work. However, during your PhD, you closely work with your supervising Professor (your advisor), who helps you every step of the way. Your advisor will be your guide, and that makes things somewhat more manageable. Your advisor will help you in selecting the right problem to solve, brainstorm with you when you propose solutions, and advise you on how to avoid pitfalls, etc. The work and the solution to the problem, of course, have to be your own—after all, it’s your PhD.

Your life is also made somewhat easier by a community of scholars—other professors and PhD students – among whom you reside. There are 50+ faculty members and postdoctoral researchers actively conducting research in the UT Dallas CS Department and another 170 PhD students. This community of scholars is there to help you, as well. Your Professor will have their own research group with multiple PhD students, and often all of the group members may be working on different aspects of a larger problem. The whole group is very much like a family and not only provides scholarly help but also a lot of emotional and moral support.

What kind of jobs can one get after doing a PhD?

The job market for PhD’s in computer science is superb. The salaries and perks are excellent too. Computer Science is a rapidly expanding field, and new areas are becoming prominent – AI, machine learning, big data, cyber security, Internet of Things, virtual/augmented reality. Companies are making significant investments in advancing these technologies as well as creating new applications for them. They are recruiting PhD graduates in large numbers at sky-high salaries, perks, and bonuses. Today, the five largest companies by market capitalization in the US stock market are technology companies – Google, Facebook, Microsoft, Apple, and Amazon.com – and they have a voracious appetite for PhD graduates.

Because of the popularity of CS as a degree major, as well as increased investments by the government in computing research, Universities are also hiring professors in large numbers. At UT Dallas, in the last five years, we have hired nearly 25 faculty members.

PhD graduates are also sought after by startups, and, in fact, many PhD graduates themselves have gone on to start their own companies. Google was born out of the research of Sergey Brin (though he never completed his Ph.D. after launching Google). Google was based on a research paper that proposed the page-ranking algorithm written while Sergey Brin was a PhD student.

Can you talk about some of the recent success stories from among your PhD graduates? 

Every year we interview every PhD graduate and post the story on our news page. Here is this year’s story about our PhD graduates . Our graduates have gone to work for top technology companies such as Google, Microsoft, Facebook, Apple, and Amazon. I should make a special mention of Dr. Ashkan Yousefpour, who just joined Facebook, after finishing his PhD in the fall of 2019. His PhD was in the area of networking and machine learning. You can learn more about his success by reading this Q&A with Dr. Yousefpour . Likewise, I should highlight Dr. Laura Moreno, who joined Colorado State University as a faculty member in 2016. You can  read more in this Q&A with Dr. Moreno.

Many people say that doing a PhD has a negative financial impact on that person. Is that true?

Far from being true, it’s actually patently false. PhD graduates of today command incredible salaries, especially if they work for large tech companies. Top earners can make salaries north of $150k per year, with a joining bonus between $50k to $100k and hundreds of thousands of dollars’ worth of stock options. Twelve-months University salaries for tenure-track faculty positions can be as high as $175,000. As a graduate with a PhD in computer science, you will always be in demand by companies, Universities, research labs, etc. A PhD in computer science indeed secures your career against economic downturns, as good computer scientists are and will always be in demand.

How long does the PhD degree take, and how much is it going to cost me?

A PhD degree will take at least four years, if not longer. Four to six years is a reasonable estimate for the range of time. The average at UT Dallas CS is perhaps 4.5 years. The good news is that nearly all our full-time PhD students have 100% of their tuition covered. In addition, PhD students get a monthly stipend ranging from $1,850 to $2,150 for covering living expenses. Financial support is generally guaranteed for four academic years. Of course, a Ph.D. student must keep making excellent progress for the continuation of this support.

Do I need an MS degree in Computer Science in order to apply for the PhD program at UT Dallas CS?

No, you don’t need to have an MS degree in advance. If you have a stellar academic record, you can apply right after your BS CS (or equivalent) degree. You will get an MS degree on the way using the coursework that you do as part of your PhD.

There are more than 200 PhD programs in Computer Science in the United States. Why should I do my Ph.D. at UT Dallas Computer Science Department?

Excellent question. There are several reasons why you should get your PhD degree in Computer Science from UT Dallas. First and foremost, we have superb faculty who are world-renowned for their research in emerging areas such as AI, Machine Learning, Natural Language Processing, Cyber Security, Software Engineering, Data Science, Internet of Things (IoT), etc. Our faculty members have received many best paper awards at various conferences, as well as many test-of-time awards, where a research paper is recognized for its long-lasting impact on the field. Seventeen of our faculty members (as of 2023) hold the prestigious National Science Foundation CAREER award—given to promising young assistant professor through a nationwide competition each year.

Second, we have an incredible system of support for our PhD students. In their first semester, all PhD students are required to take a course where they learn what research and creativity are all about, what is involved in doing a PhD, and how one can be a successful PhD student? Students get their first taste of writing a large research paper – a survey of research in their area of interest – in this introductory class. The department also organizes a weekly mixer of faculty and PhD students, where each week, one research lab briefly introduces itself and gives an overview of its research projects. The lab also provides refreshments for the mixer. In addition, the department runs a reward program, where if a group publishes a paper in a top CS conference, it gets $1,500 towards travel expenses to that conference. In addition, there are weekly seminars explicitly organized for graduate students to attend so they can get to learn about cutting-edge research in computer science. There are other opportunities, as well. For example, teaching in the summer camps that the CS department organizes for high school students, various hackathons and programming competitions, as well as many other academic, scholarly activities. The environment in the CS Department is exceptionally collegial and supportive of PhD students. PhD students are treated as an integral part of the community of scholars in the CS Department.

Third, almost all our PhD students are fully supported. They also have incredible internship opportunities available to them in the later part of their PhD, especially if they plan to pursue a career in industry.

What are the milestones that one has to cross in the PhD program at UT Dallas CS Department?

All PhD students have to pass a PhD qualifying exam in their first year (Exams in three CS subject areas spread over two semesters). Students typically find their PhD advisor in their first year and start on a program of study. They will generally identify their target area of research by their second year and begin reading-related research papers. At this time, a student may also assemble his/her dissertation committee. By the end of the second year or beginning of the third year, they would have identified a specific problem their dissertation would address, and they would start working on solving it in earnest. Once the problem that the student will solve and the approach to solving it has been identified, a thesis proposal will be made to the dissertation committee. Once the committee accepts the proposal, the student will perform the work needed to solve the problem, write the dissertation, and then present it in the final Ph.D. dissertation defense to the committee.

Any parting thoughts that you want to add?

While doing a PhD in Computer Science can be highly lucrative, you should never do a PhD for money alone. You should do a PhD for the love of learning. You should do it because you enjoy learning advanced materials in computer science, because you enjoy solving hard problems, and because you want to be known and respected for creating knowledge that will advance the frontiers of knowledge. Also, a PhD requires dedication, perseverance, and hard work, and the entrance requirements are stringent, and only academically strong students make it to the program.

Before you write your statement, start by thinking about what you want us to learn about you. Make a list of important achievements, perspectives, and goals. Build your statement around this list. We are looking for students who have made the most of the opportunities they have been presented with and who are smart, creative, and motivated. Keep in mind that we also have your CV and letters of recommendation, so we don’t necessarily need a list of all your accomplishments. However, your statement can fill in the narrative around what you did and, more specifically, why you did it. What motivates you? What are your research interests and why? These details aren’t found elsewhere in your application, so focus on them in your statement.

There are a few things we suggest not including in your statement. While it’s tempting to give a rationale for why you are applying to our program, don’t include it if it’s uninformed. Consider: “I want to apply to Johns Hopkins because it’s one of the premiere academic programs.” We know that already! If you do have specific reasons to be interested in our program (e.g. location, a specific project, a faculty member, etc.), be sure to mention them.

In terms of your motivation, be specific! Don’t write: “I’ve wanted to do a PhD in CS since I was six years old.” We don’t trust that six-year-olds make good career decisions. If you write “I have always found AREA X fascinating,” explain why.

Letters of Recommendation

The two most important factors of a recommendation letter are: 1) select someone who knows you well, and 2) select someone who knows how to write a letter.

First, it’s tempting to ask Professor X. to write a letter for you because they are a well-known person in the field. While we can better contextualize letters from people we know, it’s only helpful if the letter contains meaningful information. If Professor X. writes, “I’ve met the applicant a few times and they seem sharp,” that’s not useful information. It’s more important to select someone who knows you well and can discuss your achievements in detail.

Second, your letter writer should know how to write a letter. Academic research programs look for different things than a company. We often read letters from work supervisors that say nice things, but don’t speak to the qualities we find most important.

Of course, it’s a balance. You want someone who knows you well, but they still need to know how to write a good letter of recommendation.

We understand that three letters are a lot, especially for an undergraduate applying directly to a PhD program. We don’t expect each candidate to have three amazing letters. Your choices should be about balance: you want people who know you well, can write good academic letters, and know the research field. Use your choice of your three letter-writers to create this balance.

There isn’t much you can do about your grades—you have the grades you have. However, we do not use any grade cutoffs or thresholds in admissions. We want to see that you did well and excelled in whatever program you were in. Did you push yourself to take upper-level classes? Did you do well in the classes most directly related to your research area? If you have special circumstances that explain some of your grades, please include a description of them in your statement.

Why Get a PhD in Computer Science? Your Questions Answered

Updated: June 19, 2024

Published: August 24, 2019

Computer Science is an ever evolving and massively expanding field of study as technology continues to innovate and data grows exponentially. For those highly interested in research, earning your PhD in Computer Science can offer you top level accessibility to become an expert in the field and pursue either a high-level career within the industry or work in academia.

Most people who have completed the doctorate degree advise doing so only if you really love the subject and research. Earning your PhD in Computer Science has many benefits, although there is no doubt that it’s challenging.

Although a doctorate degree is not required to work in the field, it offers other benefits like allowing you to research cutting-edge technology with adequate funding. As with any graduate degree, it takes both time and money to complete, so before deciding to enroll, let’s go more in depth and answer some questions about why you would want to get a PhD in Computer Science.

What is a phd in computer science.

A PhD in Computer Science is the highest level doctorate degree you can earn. Once you finish your undergraduate degree in Computer Science or a related field like Engineering or Applied Mathematics, you can apply for your doctorate degree .

If you didn’t major in Computer Science, then earning your Master’s degree in the subject will help you on your journey for your doctorate degree. Although it is not required to apply for a PhD, having your Master’s degree first is generally preferable.

Most programs require the following, along with a degree, to apply for a PhD:

• Previous research experience
• Letters of recommendation
• A high GPA (about 3.5-4.0)

Program Length

Earning your PhD in Computer Science is not for the faint of heart as it requires a lot of time, energy and perseverance. Although the length of completion depends on your enrollment status of full or part-time, it typically takes 5-6 years to finish.

Opportunities and Challenges

As the top academic achievement within the field, a PhD exposes students to high-level information, as well as some of the hardest challenges facing the world and technology. A PhD grants students the opportunity to perform the research of their choice and explore the topic that interest them the most.

Upon graduation, a PhD student can continue with academia or enter the industry. However, if you want to enter the field as a Computer Programmer, Software Developer or the like, you don’t have to earn a degree at this level as a Bachelor’s degree will suffice. In fact, some jobs may consider a PhD candidate to be too highly qualified, so you’ll want to assess your future goals before enrolling in a PhD program.

One of the benefits of earning this doctorate degree is the freedom you have. Most programs are quite unstructured, meaning that you get to choose what you want to research. Therefore, you can be a leading expert in the field and help to shape policies around artificial intelligence, automation and technologies that are changing the way the world functions.

The deep and rich education can expand your horizons and help you understand ideas and topics that you would never have otherwise considered.

Potential Jobs

Although it is possible to enter the field of Computer Science without a PhD, having the knowledge will expand possibilities and increase your pay.

Some of the job titles that PhD candidates seek include:

Computer and Information Research Scientist:

People in this position help to invent new programming languages that enhance business practices. With the high amount of data, information and research, these scientists can create changes and also assess their impact through analysis.

Database Administrator:

Database administrators organize and secure data against attacks. Those with a PhD can be trusted to understand the complex nature of various systems and be able to better protect them.

Software Developer:

Software developers create systems and software for various uses. Although a PhD is not required to be a software developer, it further enhances one’s understanding.

Computer Science salaries vary based on position type, location and education. However, the overall field of Computer Science is growing. In fact, Computer and Information Research Scientists are expecting much higher than average growth with the discipline expected to increase its demand by 19% between 2016 and 2026. Those with a PhD will increase their salary potential based on their educational accomplishment.

Furthermore, with a PhD in Computer Science, you can go on to be a professor since you’re a leading expert in the field. The demand for jobs within the field is growing, especially regarding cloud computing, data storage, artificial intelligence and information security.

Online Versus Traditional Programs

The reason you choose to earn your PhD in Computer Science is personal, and how you choose to do it is also a subjective choice. It’s hard to say if an online university or traditional onsite program is better or worse because the reasons for choosing to do one or the other are different.

The benefits of an online program include relatively lower costs, more flexibility and greater accessibility. However, an onsite program offers you more opportunity to perform research and work with those in person who are already advancing the field.

For example, some students who earn their Bachelor’s degree in Computer Science online from University of the People may enjoy the online experience and therefore want to continue their studies remotely by earning their PhD online as well.

Earning your undergraduate degree is the first step in moving towards earning your PhD in Computer Science. While the field is always growing and the opportunity for research multiplies, pursuing a PhD in the discipline is an important decision to make. The program generally offers freedom to select your area of interest, but it also takes time and a lot of dedication to complete.

Those who go on to get their PhD should really have an affinity for the subject matter and love to conduct research. It’s also useful to know that it’s typically easier to earn a PhD then enter the field as opposed to working in the field and then going back to earn your PhD.

Any form of higher education will never serve as a detriment as it helps expand your mind, create more networking opportunities and better hone your skills and knowledge regarding specific subject matter.
