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.

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.

Table of Contents

Research process

For this profile, we read eight blogs by computer scientists on whether to do the PhD and reviewed the Taulbee survey ( the full list ). See all the other research we did in our wiki .

What is this career path?

In this profile we focus on doing a Computer Science PhD in the US, which usually takes 5-7 years. There is relatively low emphasis on taking classes – typically you only take classes when they are relevant to your research, and these can be in disciplines outside of computer science, including statistics, operations research, maths, psychology and linguistics. 1 The PhD is heavily research focused – by the end you write a dissertation which is a long and in depth exploration on a topic that you become an expert on.

Why do a computer science PhD?

You learn cutting edge research skills.

The most commonly cited advantage of a computer science PhD is that you learn highly advanced research skills:

• You learn the skill of choosing promising areas of research that are at the edges of a field: “Doing a PhD will force you to cast away from shore and explore the boundary of human knowledge. There’s a real trick to picking good problems, and developing a taste for it is a key skill if you want to become a technical leader.” 2
• You become fluent in both written and verbal technical communication: “I’ve noticed a big gap between the software engineers I’ve worked with who have PhDs and those who don’t in this regard. PhD-trained folks tend to give clear, well-organized talks and know how to write up their work and visualize the result of experiments. As a result they can be much more influential.” 3 This is a skill that’s important for entering data science .
• You learn to run experiments and interpret the results and get every aspect of your methodology closely critiqued.
• You learn how to read and critique research papers.

Potential for large impact from research

• During your PhD you get to work on the hardest problems at the edge of human knowledge, in a field with a strong track record of transformational research , in spite of its short history as an academic discipline. “PhD research is about opening up new avenues of enquiry, and working on problems that the rest of the world hasn’t even articulated yet. If you do it right, you can have tremendous impact.” 4 A computer science PhD opens up the potential to carry on with this research in academia or in industry.
• You have lots of freedom over what research topics to work on during your PhD (though if you want to continue to academia, you’ll need to initially focus on the topics that will most aid your career). 5
• Artificial Intelligence is one of the most important trends of the next century and is currently the most popular area of specialisation among computer science PhD’s. 6 We think it’s especially important that more people work on making sure the development of AI is done safely, and there’s increasing funding available for researchers with this aim, making it a promising area to enter . A computer science PhD opens up jobs focused on AI safety in industry (for example at DeepMind ), non-profits such as the Machine Intelligence Research Institute , and academia. If you want to work on this research, see our full review of the area .

Other benefits

• You often become the leading world expert on the area of your dissertation.
• You gain a much deeper understanding of complex computer science topics, which can help with reaching technical leadership positions in industry, which are in-demand and well-paid. 7 People with PhD’s also frequently get more freedom in their subsequent jobs than those with bachelor’s or master’s degrees. 5
• Highly intelligent peers, and close mentorship and feedback from some of the smartest people on earth.
• PhD level research can be extremely satisfying. You can discover previously completely unknown knowledge, you gain deep understanding of your area and you get to prioritise accuracy and truth over functionality and speed much more than you do in industry. 8
• It is generally easier to move from a computer science PhD into industry than it is to move from industry into a PhD. 9

Reasons not to do a computer science PhD

• It takes a long time: “Nobody finishes in four years. The typical time to completion is around five or six years, but there is a long tail — I reserve the term “paleo-student” for someone who has been at it more than 10 years.” 10
• You don’t get wide exposure to different career areas during this time – you only learn about academic computer science.
• Currently only around 30% of computer science PhDs get jobs in academia, with less than 10% getting tenure track positions. 11 To get a tenure-track position it is increasingly necessary to do one or more post-docs first, meaning you face even more time with relatively low pay. 12
• Currently only around 55-65% of those who get jobs in industry after their PhD get research positions (suggesting it may have been better for them to enter industry directly). 13 Overall, only around half of computer science PhD’s get research positions immediately after their PhD’s whether this is in academia or in industry. 14
• The PhD is extremely unstructured – you do highly open-ended research with no clear guidelines on progress or how to organise your time. “Research can be very rewarding and very frustrating. Most students describe graduate school as a roller-coaster with tremendous highs and tremendous lows.” 15
• The pay is not that high – median stipends range from $17,000 to $29,000. 16

Entry requirements

You need an undergraduate degree in computer science or a closely related field like engineering, maths or physics (or another major as long as you took a lot of CS classes). A master in computer science can help you enter if your major wasn’t in computer science and you haven’t taken many CS classes. 17

You also typically need:

• Previous research experience
• Excellent letters of recommendation from researchers who can comment on your research ability
• A high GPA (3.5-4.0) in computer science and maths classes and quantitative reasoning GRE scores over 650. 18

Who should most strongly consider a computer science PhD?

You should only consider a computer science PhD if you are incredibly motivated to do high-level computer science research. All the advice we read was emphatic on this point. Here is a representative quote:

The only reason to do a PhD is because you love doing research. If you don’t love research, don’t bother — it is not worth the time, money (in terms of opportunity cost vs. making a real salary in industry), or stress. 19

To get a sense of what academic research in computer science is like, try reading published papers (see for example this paper and this paper ).

Given that only 10% end up with tenure track positions and of those that enter industry immediately after the PhD only 50% end up with research positions, it’s unclear whether the PhD is worth the considerable costs for the bottom 50% or so of candidates.

Overall, especially consider a computer science PhD if:

• You meet the entry requirements.
• You’re highly motivated to do computer science research.
• You expect to be among the top 30% of PhD candidates.
• You want to go into computer science academia or do high-level research in industry, especially if you want to work on artificial intelligence .

Notes and references

• “In contrast, a Ph.D. program typically requires typically less than 10 courses during the entire 6 years (at CMU there are 5 required “core” courses, and 3 required “electives”). The emphasis in the Ph.D. is not on classes, but rather on research. A Ph.D. student will typically take classes only when she feels that they will be useful in her research. The classes she takes may not even be in CS at all. They may be in Statistics, Operations Research, Math, Psychology, Linguistics, or anything else useful for her particular research topic.” Applying to Ph.D. Programs in Computer Science – Carnegie Mellon University ↩

Typically, people with Bachelor’s and Master’s degrees aren’t afforded so much freedom.” Matt Welsh – So, you want to go to grad school? ↩

• “I do think that doing a PhD is useful for software engineers, especially those that are inclined to be technical leaders. There are many things you can only learn “on the job,” but doing a PhD, and having to build your own compiler, or design a new operating system, or prove a complex distributed algorithm from scratch is going to give you a much deeper understanding of complex Computer Science topics than following coding examples on StackOverflow.” Matt Welsh – Do you need a PhD? ↩
• “For all the frustrations, research can be extremely joyous. For some people, the joy of research is the joy of discovering something new that no one knew about. You might be discovering a new algorithm, a new operating system design idea, a new idea for maximizing the performance of disk arrays, etc.. For others, there’s the joy of truly understanding. You’ve probably noticed that in classes a professor or book will stop just when things are getting really interesting and say, “the rest is beyond the scope of this class.” In research, you can take a problem as far as you want and understand everything about it. For many, the joy of research comes from being able to make an impact – to change the way systems are built and design them in a smarter way. There’s also the joy of doing it right. In a company, the aim is to get a working product and ship it out quickly. In research, you can take your time and plan out your project so that you are proud to defend every one of your design decisions. Research is not about simple heuristics or quick hacks. Many people also relish the joy of being the authority on an area and of having their work read and cited by others.” Applying to Ph.D. Programs in Computer Science – Carnegie Mellon University ↩
• “In my experience, it is quite rare to make the jump from industry to grad school. First off, industry pays so much better than the PhD student stipend that it is quite hard to make this transition. Also, to get into a top PhD program, you need good letters from CS professors, and letters from industry don’t really count. After you’ve been gone for a couple of years it’s hard to get those stellar letters from the professors that may have loved you back when you were in college; newer, brighter, more energetic students have taken your place and you are long forgotten (although maybe Facebook will change all that). Industry experience rarely helps a graduate application, especially if you’re some low-level engineer at a big company writing tests all day.” Matt Welsh – So, you want to go to grad school? ↩

Since 2007, hiring of Ph.D.’s in academia is increasingly dominated by postdoc positions rather than tenure-track positions. The requirements for a tenure-track position appear to have been redefined to make one or more postdocs nearly mandatory. This has been the case in other disciplines for a long time, but it is relatively new for Computer Science.

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

Is it worth it to get a Masters or PhD in CS?

I'm very much considering getting my PhD in computer science because I'd like to go on to do AI research. I'm currently in my last year of undergrad. I have a high GPA and a couple of years of research experience, so I don't think I'll have any trouble getting into a program. The issue is, while I'd like to do research in computer science, particularly artificial intelligence, I don't want to work in academia.

I have a friend who went on to work immediately after getting his bachelors, and he tells me that getting my Masters or PhD can hurt me in the long run, as it will limit my career options. He claims that employers don't want to hire grad students when they're "overqualified", and that there are far fewer jobs for grad students. He also claims that the pay difference isn't worth the extra years in school.

My thinking is that I'd rather do research, so having a graduate degree is important; employers want it, and it's the best way to learn more in-depth about the interesting topics in CS. I also don't think "overqualified" is going to be a problem. I claim that employers use that term when they're afraid that recent hires will immediately move on when a better opportunity comes, but if options are as limited as he claims, then that won't be an issue anyway. I also am sure that given my high GPA at a good school, relevant work experience, and motivation, I can get into a good program and will be paid for school.

I've talked to the professor I'm currently working for, and he says that good people get good jobs, and that I shouldn't worry. I've done some research online, but I'd really rather hear from people actually out there working. What do you guys think?

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 .
