Doctoral Admissions

Students applying to the Ph.D. program in Computer Science or interdisciplinary degrees the Computer Science Department co-manages must apply online. 

Apply to the Ph.D. in CS & Interdisciplinary Degrees

To apply to the Ph.D. in CS program you need to use the School of Computer Science Online Application.  

To apply to an Interdisciplinary degree program you need to apply via the online application for the Ph.D. in CS and select the interdisciplinary program (ACO, CNBC, PAL) in the appropriate section of the online application.

Students are admitted for the fall semester and cannot begin in the spring.

Applications for all programs and all supporting documents, including letters of recommendation, must be received by the final deadline of December 13, 2023.

Required Documents & Support Materials - All Programs
You must submit the following with your application:
Graduate Record Exam (GRE):
GRE scores are optional. An application without GRE scores is not at a disadvantage; however, applicants who have taken the GREs are encouraged to submit their scores. The GRE at Home Test is not accepted.
Language Exams:

If you will be studying on an F-1 or J-1 visa, and English is not a native language for you (native language is defined as spoken at home from birth), we are required to formally evaluate your English proficiency via one of these standardized tests: 

  • TOEFL (preferred)
  • IELTS
  • Duolingo

We do not accept the "TOEFL ITP Plus for China,” since speaking is not scored. Applicants currently in mainland China are encouraged to take the IELTS test. 

The Computer Science Department follows the Language Proficiency Policy set by the School of Computer Science and does not issue waivers for non-native English speakers.

Please refer to details on the SCS Frequently Asked Questions page and in the Graduate Application Instructions.

Transcripts:
A PDF of your most recent transcript from each college and/or university you attended, even if no degree was granted.
Resumé/CV:
Your resumé or curriculum vitae in PDF format.
Statement of Purpose:
Include a concise one- or two-page essay describing your primary research interests, related experiences and objective in pursuing a Ph.D. in computer science.
Letters of Recommendation:
We request 3 letters, at least two of which are from faculty or recent employers.
