Computer Science (Ph.D.)

Basic Degree Information/Description

The Department of Computer Science offers advanced coursework and research leading to the Doctor of Philosophy degree in computer science. The program provides cutting edge research experience as well as expertise in advanced computer science subjects, aiming at educating future leaders in academia and industry. Successful Ph.D. candidates must demonstrate an in-depth knowledge of computer science and must deliver an original contribution to the field.

Why pursue a Ph.D. in Computer Science?

  • The Department of Computer Science offers comprehensive programs at both undergraduate and graduate levels, with approximately 400 undergraduates, 80 M.S. students and 70 Ph.D. Students.
  • The program offers opportunities for students to do advanced research in many fields in computer science. The research activities and experimental facilities have been well-supported by various federal research and infrastructure grants.
  • Applicants will automatically be considered for scholarships, and teaching assistantship and research assistantships.  Support for a typical Ph.D. student offers financial compensation of $18,000 or more per year (12 months) in addition to covering tuition and fees.
