Undergraduates wanting to major in computer science first apply through one of four undergraduate schools:

Each school has its own application procedure; however, online information is centralized under Applying to Columbia.


Applications received and considered complete by these priority deadlines will be reviewed in the first or second priority group of applications. We recommend you submit your application a couple of weeks before the priority deadline to ensure that all materials including recommendation letters are received in time for priority review.

The Master of Science (MS) program is intended for professionals who wish to broaden and deepen their understanding of computer science. Columbia University and the New York City environment provide excellent career opportunities with multiple industries. The program provides a unique opportunity to develop leading-edge in-depth knowledge of specific computer science disciplines.

MS applicants whose primary interests include software engineering, theory, AI, machine learning, vision/graphics, natural language processing, or other core CS areas should apply to the Computer Science MS Program.

MS applicants whose primary interests include computer architecture, parallel systems, embedded systems, or digital/VLSI design should apply to the Computer Engineering MS Program.

MS Thesis


Admitted students will enroll for a total of five semesters — approximately three in The Fu Foundation School of Engineering and Applied Science and two in the Journalism School. In addition to taking classes already offered at the Journalism and Engineering schools, students will attend a seminar and workshop designed specifically for the dual degree program. The seminar will teach students about the impact of digital techniques on journalism; the emerging role of citizens in the news process; the influence of social media; and the changing business models that will support news gathering. In the workshop, students will use a hands-on approach to delve deeply into information design, focusing on how to build a site, section or application from concept to development, ensuring the editorial goals are kept uppermost in mind. For more information, visit the program website.


The Columbia University Department of Computer Science is looking for top-quality students to join its PhD Program. The department hosts exciting projects in a growing number of research areas. (See below.) Columbia University is located in New York City, one of the cultural, financial, and communications capitals of the world. This central location makes it possible for the members of the Department of Computer Science to have close ties with the nearby research labs of virtually all major technology companies, as well as with a number of major companies including financial companies of Wall Street.


A small number of highly qualified students are admitted each year to the PhD Program in Computer Science. Admission is very competitive, based primarily on research-oriented reference letters, academic grades, and overall experience and record. Applicants need not already hold a master’s degree; bachelor’s degree level applicants are also encouraged to apply.

Most admitted students receive full financial support through Graduate Research Assistantships, which consist of a monthly stipend plus full tuition exemption (continuation of support is, of course, contingent upon the students’ satisfactory progress in the PhD Program and availability of funding). In addition, the Fu Foundation School of Engineering and Applied Science awards a small number of prestigious “Presidential Distinguished Fellowships.” These fellowships provide full financial support to their recipients. Applicants are strongly encouraged to seek external funding, such as government and industry fellowships. Also, Columbia rents low-cost subsidized apartments near campus for both single students and students with families.

All PhD students are expected to participate in departmental and laboratory activity full-time on-campus throughout the program, except possibly for summer internships elsewhere. Therefore, the department does not normally consider admission of part-time students. Also, note that it is not possible to participate in the PhD Program through the Columbia Video Network.


All applications to our PhD Program must be made electronically. The online application system is available on the SEAS Admissions website. The deadlines for the submission of your fully completed application are:

  • To start the PhD Program in the Spring semester: apply by November 15 of the previous year.
  • To start the PhD Program in the Fall semester: apply by December 15 of the previous year.

You can still apply after these deadlines. However, be aware that applications are usually reviewed soon after the deadline, so late applications may not be processed as quickly or have the best chance of getting funding from our department.


The comprehensive frequently asked questions (FAQs) and the SEAS Admissions website both contain detailed information about all aspects of the application process.

You are also encouraged to investigate the research conducted in the Department of Computer Science prior to application. In particular, think about which faculty members share your research interests and also look at the research group homepages. Feel free to contact potential faculty advisors by email to request information about their recent research and publications, and to ask about opportunities in their research groups or labs.

Finally, become familiar with our PhD degree requirements.

If you are interested in learning more about a day in the life of our PhD students, check out the Demystifying the Dissertation: PhD Research Discussions seminar series, which highlights several Computer Science PhD students. In their videos, these students discuss their experiences and research projects. This series is a CS Student Services initiative and its goal is to help undergrads, master’s students, and alumni understand the often mystifying world of PhD research and the dissertation process. Watch the series here.


As we enter the 21st century and beyond, Science, Technology and its related fields – including Computer Science – will play a key role in shaping the future of our society.  Institutions such as Columbia University will be instrumental in working on the most important problems in the field as well as educating the next generation of academics and researchers who will go on to make their own invaluable contributions.  In light of this reality, a group of current PhD students in the Computer Science Department are helping to establish the most accessible PhD application process possible, to promote a diverse and welcoming intellectual environment for all. This volunteer-run program is one part of our ongoing efforts to achieve this goal.

The CS Department recognizes that our field as a whole has not succeeded in empowering under-represented populations to take advantage of CS research and professional opportunities.

This lack of representation in CS leads to systematic disadvantages to applicants in those communities which can manifest in several ways, including (1) difficulty in accessing research mentorship at their university or elsewhere, (2) lack of exposure to seminars and events around recent research, and (3) difficulty in accessing application mentoring on how to best advertise their past experiences and aspirations when applying to a specific discipline within CS.

Motivated by this (and a similar initiative underway in the Stanford CS Department), the CS Department is running a program where PhD applicants can receive a one-time review of their Personal Statement and Resume/CV before making their final submission. The review will be done by a current PhD student (from the sub-area of CS that the applicant is interested in pursuing). Note that this program is separate from the admissions process: program reviewers do not sit on the admissions committee, and whether or not an applicant is selected to receive review does not reflect their chance of admission to the PhD program.

Please note that this is a Student-Run Volunteer Program. Participation in this program is first-come, first-served and dependent on the availability of our volunteer PhD reviewing pool. The form for submitting your Personal Statement and Resume/CV is here. The deadline for submitting your materials is November 7, 2021, at 11:59 pm EST. You will be notified by November 14, 2021. if your personal statement and resume/CV will be reviewed. And you will hear back from the reviewer no later than no later than November 21, 2021.
