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 two 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: the Computing Track and the Information Systems and HCI track. Students pursuing PhD topics in typical computer science areas such as algorithms, artificial intelligence, databases, data mining, programming languages, software engineering, etc. follow the Computing Track. The Information Systems and HCI Track is for students whose topics fall under the category of information systems or Human Computer Interaction.  Students must choose whether to enter the Computing or Information Systems and HCI Track at admission.
