Online Ph.D. in Computer Science Programs

Computer science is the study of computers and computation. It incorporates mathematical models, data analysis, software engineering, and information security. Careers in this field include user design, software development, database administration, and systems analysis. Most of these careers require a bachelor’s degree or higher to get started.

For experienced professionals, a Ph.D. in computer science can provide a pathway to chief technology officer and computer science professor careers. Earning your doctorate online means you can study from home while maintaining your professional and personal responsibilities.

A Ph.D. in computer science is the highest degree in the field, and it can prepare you to pursue roles in leadership, research, and academia. In this program, you take advanced computer science coursework and may specialize in a subfield such as cybersecurity. A Ph.D. also includes a series of research courses.

This program usually requires 72-90 credits beyond a bachelor’s degree or 60 credits more than a master’s degree. Whether on campus or online, a Ph.D. in computer science concludes with a dissertation, which is an original research project. This degree is available in online, hybrid, and residential formats, though in-person programs are most common.

Doctor of Information Technology: A DIT emphasizes advanced practices in applied technology leadership. This 3-4 year degree requires a technology background — often a master’s degree in information technology and three years of experience in the field. The program may conclude with an applied research course sequence and project in place of a dissertation.

Doctor of Computer Science: A DCS blends theories, applications, and research in computer science. This 3-5 year degree may include specialization options such as big data analytics or cybersecurity and information assurance. DCS students research and write on industry-relevant trends as part of their final projects.

Doctor of Science: Like a Ph.D., a D.Sc. is a research-oriented doctorate but applies exclusively to a STEM field. A D.Sc. in computer science can focus on computer science theory or applied research. This program requires about 60 post-master’s credits.

Doctor of Engineering: A D.Eng., like a Ph.D. in computer engineering, is a research-oriented degree. Instead of emphasizing computer science theory, however, this degree focuses on solving real-world computer engineering problems. A D.Eng. may require 2-4 years beyond the master’s degree.

Doctor of Education: An Ed.D. is a three-year doctorate focused on teaching, school administration, or applied education research. An Ed.D. in computer science can help current K-12 teachers expand their knowledge of computer science education but does not usually prepare students for initial teaching licensure.

Use the following table to find and compare schools that offer online or hybrid doctoral programs in computer science. All schools listed are nonprofit, institutionally accredited, and in the United States.

An online Ph.D. in computer science typically includes a mix of traditional coursework, a research course sequence, and a final research project (usually a dissertation). A dissertation often comprises 12-18 credits, must make an original contribution to the field, and requires approval from faculty.

A professional or practice-based program may require you to investigate an applied research problem, whereas a traditional program may emphasize computer science theory. Some programs offer concentration options, which allow you to focus your coursework in a particular subdiscipline of computer science.

Computer science courses may include:

Possible concentrations may include:

In the U.S., an accredited school has undergone a rigorous review process with a private organization to ensure that it meets minimum standards of governance, financial stability, and academic quality. Accreditation occurs at the institutional and programmatic levels.

Institutional accreditation signals that a third-party company has approved the entire college or university. Institutionally accredited schools can offer access to financial aid, and their degrees are recognized by employers worldwide. Most institutional accreditors are regional bodies, such as the New England Commission of Higher Education.

Programmatic accreditors only approve individual departments or programs within schools. ABET is the main programmatic accreditor for computer science, but this organization does not accredit doctoral programs. However, the presence of ABET-accredited bachelor’s programs could be an important quality indicator when comparing doctoral programs.

An online Ph.D. in computer science can raise your salary potential and qualify you for more leadership opportunities in tech. Many professionals with computer science Ph.D. degrees make six figures working as computer scientists, computer systems analysts, and computer network architects.

The table below highlights some career paths you can follow with this degree. Research and business jobs can offer some of the highest salaries for computer science graduates.

The National Center for Education Statistics reports that a research doctorate in math, engineering, or computer science costs an average of $25,260 in annual tuition. A professional doctorate in these fields costs an average of $18,342 per year. Some in-person doctorates offer research or teaching assistantships that can cover up to 100% of your tuition costs, along with a living stipend.

Some schools require you to hold a master’s degree to apply for their Ph.D. in computer science, but other programs accept applicants with bachelor’s degrees in the field. A few programs award master’s degrees as part of the pathway to Ph.D. degrees.

The journey to any Ph.D. is long and rigorous, and as a STEM field, computer science can present many challenging courses and concepts. Consequently, a computer science Ph.D. is an especially tough degree for many students to earn. However, with perseverance and preparation, many people complete their computer science doctorates each year.

An on-campus or online Ph.D. in computer science typically requires 72-90 credits total or 60 credits for a student who holds a master’s degree in the field. Depending on your academic preparation and whether you study part time or full time, your degree may take 3-5 years. Most Ph.D. programs only permit students to enroll for seven years.

As of July 2024, Payscale reported that people with Ph.D. in computer science degrees earned an average salary of $139,000 per year. Senior data scientists, software engineers, and chief data scientists with doctorates may earn more. Only you can determine if these roles and salaries justify the time, energy, and expense required to earn a Ph.D.
