Students must have an undergraduate degree in computer science or an allied field such as engineering or math with appropriate CS background to be admitted into the Ph.D. program. Each student who is admitted should satisfy the following requirements:
The following UTCS undergraduate courses, or equivalent, are required as background (not prerequisites, can be met after admission):
- Architecture (CS 352) or beginning Spring 2012 (CS 429)
- Operating Systems (CS 372) or beginning Fall 2012 (439)
- Programming Languages (CS 345) or Compilers (CS 375)
- Theory of Computation (CS 353) or Algorithms (CS 357) or beginning Fall 2012 (CS 331)
A student can satisfy the background requirement using one of the following options:
- Subject GRE in CS with score of 90-percentile last offered April 2013, ETS will report scores through Spring 2018; OR
- Undergraduate coursework that covers the background topics through any combination of:
- Courses taken prior to admission
- Background courses named above may be taken at UTCS as a graduate student. An overall GPA of 3.50 on courses taken at UTCS is required unless only 1 course is taken, in which case the requirement is for a 3.0 in that single class.
- Student receives a B or better on Final exam(s) of UTCS undergraduate background courses.
Every PhD student is expected to spend a substantial amount of time on research, starting from the first semester. Doctoral students are required to enroll in a special research course CS 398T during their first semester in the program. (Students entering in Spring will be required to take this course the following Fall.) As part of this class, students will be expected to find a research supervisor with whom the student will work throughout the first year; each PhD student must always have a research supervisor.
In each subsequent semester, until admission to candidacy, a Ph.D. student must enroll in and complete a CS395 (Research Course) with a research supervisor. (Please submit the necessary form to the graduate office.)
Doctoral students may not enroll for 12 or more hours unless they receive special permission from the Graduate Advisor. Such permission is granted rarely.
The goal of the diversity program is to expose students to different research styles and methods from various CS areas.
Each student must take one diversity course from each of five to seven different threads, with no more than two threads in each of the three areas:
See Diversity Courses for a list of the Diversity courses that are offered and their grouping into threads.
Courses used to satisfy the Diversity requirement should be completed with a grade of B- or better, and a combined grade point average of 3.5 must be achieved on the 5 courses used to satisfy the Diversity requirement. An overall grade point average of 3.1 must be maintained on all Diversity courses taken. Additional Diversity courses may be taken as part of the Depth program. Diversity courses may not be taken CR/NC due to the GPA requirements.
Diversity Course Waivers may be used to fulfill some Diversity requirements. A Diversity Course Waiver is granted when: (1) a student has taken a graduate-level course at another university and that course is equivalent to a UT-CS Diversity course, and (2) the student is able to demonstrate a satisfactory understanding of this material to a Graduate Studies Committee (GSC) member who teaches the Diversity course. The GSC member may choose any method to evaluate the student's knowledge: a written or an oral examination is possible. The GSC member sends an email with their approval of the diversity course waiver to the CS program coordinator for final approval at the next GSC meeting. At most one Diversity Course Waiver may be used in each Diversity area.
Students satisfy this requirement by taking at least 3 courses related to their particular research interests. At most one of these courses may be outside the Computer Sciences Department; they are usually chosen from the CS department's list of graduate classes. No course used to satisfy the minor requirement for the Master's may be used. Courses listed as Diversity courses may be used as part of a depth program as long as they were not also used in the student's Diversity program. No CS 395 (conference) or CS 398T course may be included in a Research Qualification (RQ) document. All courses used to satisfy this requirement must be completed with a grade of B or better. A grade point average of 3.6 over all depth courses must be attained.
Research Preparation Exam
The Research Preparation Exam requires students to learn and demonstrate specific skills necessary to do research early in their careers. Please send the title, date, time, place, short abstract, and committee members for your RPE to email@example.com when you have scheduled it. The CS faculty and students will be notified.
For this exam, the student (in consultation with faculty) selects and conducts research on a topic, and presents a talk, to be approved by a committee of 3 UT GSC faculty members. The chair of the RPE committee should be a CS GSC member and one of the committee members should be from outside the student's research area. The committee will evaluate the student with respect to two questions:
- Has the student demonstrated scholarship and potential to conduct original research?
- Has the student demonstrated ability to communicate technical content effectively to a general-CS audience?
A student should pass the exam by the end of their 3rd year in the PhD program (before filing the Research Qualification document). It is not necessary to complete all coursework before doing the RPE. Following the RPE, an email should be sent by the chair of the committee to the graduate adviser and the CS graduate program coordinator with a copy to all committee members indicating the student successfully completed the RPE requirement.
Research Qualification (RQ) Document
In the RQ document, the student:
- provides evidence of satisfying the background requirements
- submits coursework (5 Diversity courses completed and 3 Depth courses, some of which may remain to be taken) with satisfaction of the GPA requirements
- provides evidence of completing the Research Preparation Exam
- formalizes dissertation advisor(s)
The RQ document must be filed by the end of the 3rd year in the PhD program.
Dissertation Proposal and Advancing to Candidacy
Each student must prepare a written dissertation proposal and then give an oral public presentation of the proposal. This will normally happen soon after the RQ document is filed. Please see advancing to candidacy for more information on this requirement.
Dissertation Final Defense
Each student writes a dissertation that describes original research and submits it to the members of the dissertation committee. There are many resources available to assist in writing a dissertation. Please see final defense to read the steps for the defense.
A minimum grade point average of 3.0 must be maintained over all CS graduate courses. All course requirements must be completed within a six-year period. There is a two-semester requirement for Ph.D. Candidacy. The first semester requires enrollment in _99R and the second semester requires enrollment in _99W. A student may enroll in a summer session as part of the 2 semester enrollment requirement.
The Requirements of the Graduate School
The Graduate School imposes a set of requirements on all graduate students, which must be met by all CS graduate students. These requirements deal with such issues as grades, courses taken in residence, transfer credit, and time limits. If you are unsure about a requirement please speak with the CS graduate office.
Earlier Doctoral Program
Doctoral students who first enrolled prior to January 2006 may choose to graduate under the new rules above or under the earlier program. See the former Ph.D. program for a description of the earlier Ph.D. program.
Parallel Masters Study
Ph.D. students may also pursue the M.S.C.S. degree as long as it does not interfere with their pursuit of the doctorate. The course requirements for an M.S.C.S., other than the background courses and two additional courses for a minor, are a subset of those for the Ph.D. Students must obtain approval of the graduate adviser and their research supervisor before taking a minor course. Send an email to the graduate adviser with a scholarly justification of the reasons leading to choosing the minor course(s). The student's research supervisor should send an email to the graduate adviser and copy the CS program coordinator indicating approval of the minor course(s) choice.
