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 PhD thesis 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.
