The Ph.D. in Computer and Information Sciences offers an opportunity for exceptional students to pursue substantial research in the computer sciences and related areas. To earn a Ph.D. degree, a student must demonstrate breadth of knowledge in at least three research areas and significant depth in a chosen dissertation area. In addition, the student must conceive, write and defend a Ph.D. dissertation representing a significant and original contribution to current academic research as demonstrated by a public dissertation defense and publication in established peer-reviewed academic conferences and/or journals.

The Ph.D. in Computer and Information Sciences has two tracks, which differ primarily in the structure of the Inquiry Phase. Students must choose whether to enter the Computer Science or Information Systems track at admission.
