PhD Computer Science
The objective of the PhD in Computer Science is to produce outstanding computer scientists who are capable of conducting high-quality research with a deep understanding of their research domain. Our PhD will prepare graduates with the potential to make significant contributions to the academy and in the private sector.
The PhD in Computer Science is a full-time, four-year program (12 semesters) during which students will complete the Technical and Communication Research Methodology course (CIS*6890) and two additional graduate courses selected in consultation with their Advisory Committee. Students will also give two public seminars, pass a qualifying exam, conduct research and successfully defend a written dissertation at the final oral examination. Applicants also have the option to apply for a collaborative specialization in One Health while pursuing a thesis-based PhD degree in computer science.
We strongly encourage all applicants to get in touch with prospective Graduate Faculty Supervisors prior to applying to the PhD in Computer Science program, as finding a SoCS supervisor is mandatory for admission. You can review SoCS Faculty Areas of Research to assist you in finding a suitable SoCS graduate faculty supervisor.

Successful applicants will also demonstrate good research potential, an ability to critically evaluate experimental or theoretical results and strong communication skills. Evidence for these may be provided by scholarly publications during and/or immediately following their master's degree.
- A minimum B admission average: Applicants are required to have a minimum admission average of 75% ('B') during the previous two years of full-time university study for a graduate degree.

Admission average needs to be equivalent to a ‘B’ at the University of Guelph.
- A SoCS faculty supervisor: Each PhD candidate will conduct thesis research by working closely with a chosen SoCS faculty thesis supervisor. We strongly encourage all applicants to get in touch with prospective Graduate Faculty Supervisors prior to applying, as finding a SoCS supervisor is mandatory for admission into the PhD.CS program.
You can review SoCS Faculty Areas of Research to assist you in finding a suitable SoCS graduate faculty supervisor. Please also review Tips for Finding a Supervisor to assist you in communicating effectively with our SoCS faculty.
