The Computer Science PhD program is divided up into a series of milestones which every student progresses through on the way to the degree.
CS 7001: Introduction to Graduate Studies
During students' first semester at the College, they are expected to enroll in CS7001, Introduction to Graduate Studies. This course helps prepare students for research in computer science, and provides an introduction to the various research areas in the College.
Research Credit Hours
Research with a faculty member is an essential aspect of the Computer Science Ph.D. Newly admitted students are expected to work on one or more jointly-defined research projects with faculty members in the College. While one goal of this is for the student to gain practical experience in doing research, these semester-long projects also serve as a way for students and faculty to begin to explore potential advisor relationships.
Before students have a formal advisor, they are expected to register for CS 8903, Special Problems in Computer Science, under the supervision of a faculty member in the College. Registration for this course is restricted, and requires that students and the supervising faculty member complete a form describing the research to be completed over the course of the semester. Students may occasionally participate in multiple 8903 research projects in any given semester, given time and other commitments, and may participate in 8903 research projects for several semesters until they have a formal research advisor.
Once students have a formal advisor, they are expected to focus on what will become their dissertation research under the supervision of their advisor. At this stage, students will register for CS 8999, Doctoral Thesis Preparation. Students and their advisor must fill out the CS 8999 permit form that indicates the general research direction and that confirms the establishment of the advisory relationship. This form only needs to be filled out one time.
After admission, a student begins to work on fulfilling the breadth requirement. The breadth component of the program is intended to give students a view into a variety of areas within computing. Each student must take classes in 5 of the 15 areas of computer science. The 15 areas are:
Of the five different courses, one must be from the Theory area. Students must earn an A or B in all of these courses, and more As than Bs total.
Students who have taken graduate level courses elsewhere before entering the program can petition to have those classes count towards filling the breadth requirement.
Programming Proficiency Requirement
In addition, each student must complete a Programming Proficiency requirement. A single class may satisfy both the Programming Proficiency requirement and a Breadth area requirement. The Programming Proficiency requirement must be fulfilled at Georgia Tech and may not be satisfied by transfer credit or advanced standing.
The courses that can satisfy the Programming Proficiency Requirement are:
- CS 6210 Advanced Operating Systems
- CS 6241 Design and Implementation of Compilers
- CS 6290 High-Performance Computer Architecture
- CS 6476 Computer Vision
- CS 7637 Knowledge-Based AI
- CS 7646 Machine Learning for Trading
- CS 7650 Natural Language

The minor is a sequence of non-College of Computing courses with a coherent theme, totaling 9 credit hours. Their theme should somehow relate to the subject of the student's thesis and research.
The classes must be taken for a letter grade, with at least a "B" average. Courses should be at the graduate level, but one approved 4000-level course may be used. No more than three of the hours may be directed research.
After completing all the minor classes, download and fill out the Minor form.
As a student's research progresses, he or she must select a primary, and possibly secondary, area of focus from the areas of research in the College and then pass a Qualifier in that area or areas. The Qualifier is a student's first step toward achieving candidacy in the doctoral program. This Qualifier functions as Georgia Tech's Comprehensive Examination. Click here to view the list of areas of research in the College identified for the Qualifier and Breadth Requirements.
The Qualifier consists of three parts:
- A one-day written examination covering the pertinent research area(s). It will typically be near the tenth week of the semester. All students taking the exam at the same time in an area take the same exam. This component evaluates the student's depth of knowledge in his or her chosen areas.
- The submission of a high-quality research deliverable, as evidenced by a portfolio consisting of an exam-committee-reviewed and publishable article, and possibly other work products as approved by the exam committee. This component evaluates the student's creative and research abilities, along with the potential to do dissertation research.
- An oral presentation and examination which also allows for follow-up on the first two parts.
The Exam Committee
The student must identify a research advisor and an exam committee of at least three other faculty from the area to oversee the Qualifier.
- The exam committee is responsible for determining if a student has passed the Qualifier. The results of the Qualifier will be communicated to the PhD. coordinator by the respective area advisor. The student should fill out the Qualifier Form after passing the Exam.
- Each student is allowed two opportunities to pass both the area knowledge and creativity components of the examination. The two components are treated independently, so a student need not pass both at the same time. Students who are not able to pass the Qualifier after two attempts will be encouraged to seek a Master's degree, and they will not be able to continue in the doctoral program.
- After successfully completing the Qualifier, student focuses on research leading toward a dissertation. Students should register for doctoral dissertation hours (CS 9000) after passing the Qualifier rather than registering for Special Problems (CS 8903).
The topic of the student's research is formalized through both a written dissertation proposal and an oral presentation.
Students need to register for a Qualifier prep course during the term they plan to take the Qualifier:
- CS 7999 - Register for between 3-6 pass/fail hours. This course is permit only. Email your permit request to the PhD Coodinator in Student Services.
At the beginning of each semester, the PhD. coordinator will send out a message to all PhD. students asking for the names of those who want to take the Qualifier that semester. Students who intend to take the exam must respond to this message.
Attend the Orientation Meeting
In a meeting soon thereafter, the PhD. coordinator will explain the process to these students. A date for the exam will also be set during this meeting.
Take the Written Exam
On the exam day, pick up the exam from Barbara at 9am. If you are from another building, you can pick it up from her at 8.45am. You have until 5 p.m. that day to complete the exam. Return your exam to the PhD. coordinator by 5 p.m. that day. Again, if you are from another building, you have until 5:15 p.m. to return the exam.
Create a Research Portfolio
In consultation with your advisor and the committee, assemble a research portfolio before the oral exam. The nature of the portfolio is decided by the committee. The portfolio shall be handed over to the exam committee at least one week prior to the oral exam.
Schedule the Oral Exam
Schedule an oral exam in consultation with the committee. The oral exam should preferably be held before the end of the semester. The oral exam date and the names of the exam committee members should be communicated to the Ph.D. coordinator in Student Services.
The PhD. proposal consists of:
- A proposal document written by the student in which he/she will propose the research work to be undertaken as part of his/her doctoral work and a schedule for completion
- An oral defense of the proposal document
PhD. proposal will be administered by the student's thesis advisory committee (the advisor plus at least two other faculty members), chosen jointly by the student and the advisor. A majority of the members of the advisory committee must hold their primary appointments on the College of Computing faculty. It is a good practice to have all members (including the external committee member) of your dissertation defense committee in your proposal committee.
The proposal must be announced publicly to the College at least one week prior to the date of the oral defense. Please provide a copy of the announcement to Ph.D. Coordinator in Student Services.
There is no fixed format for the oral defense. The advisor, as the chair of the committee, conducts the examination. Here is a typical way in which it may be run:
- The student will make a presentation to the committee and others present.
- After the presentation there is a question and answer period. The chair then asks everyone other than the committee members and Georgia Tech faculty to leave. The committee members then have an opportunity to ask more questions. Then the student is asked to leave.
- The committee deliberates and then decides whether the student has passed the proposal defense. They give feedback to the student on the proposal either individually or through the advisor.
A student must have passed the qualifying examination to do a PhD. proposal. A student who has passed the proposal defense and has also completed all course requirements (except the minor), maintaining a satisfactory scholastic record, has achieved PhD. candidacy and should submit the Candidacy form.
Before the announcement of the public PhD. dissertation defense, your advisor must approve that the dissertation is ready to be given to the dissertation committee, and the dissertation committee must approve that the dissertation is ready for the public dissertation defense. Before giving this approval, the entire committee is expected to have read the dissertation and to have given comments to the student. The committee must approve that a substantial and defensible portion of the dissertation has been completed. Three (3) weeks is a reasonable amount of time for reading the dissertation.
After the approval, the candidate’s academic department must announce the public dissertation defense at least fifteen (15) days in advance, and it must forward this announcement together with the names of the dissertation committee to the Office of Graduate Studies and Research.
The public dissertation defense starts with a presentation by the candidate and is followed by a question-answer period. The advisor, who is the chair of the committee, determines who may ask questions and in which order and brings the discussion to a close at the appropriate time. The question-answer period is followed by a closed-door session attended by only the members of the PhD. dissertation committee and interested Georgia Tech faculty.
The dissertation committee must take one of the following actions:
- To approve the dissertation without corrections.
- To approve the dissertation with minor corrections, to be approved by the advisor only.
- To require a resubmission with major changes and re-approval by the entire committee.
- Not to approve the dissertation.
The dissertation committee may recommend one additional defense if the dissertation is resubmitted with major changes or if the dissertation is not approved.
The candidate must make any corrections deemed necessary by the dissertation committee and the committee must sign the dissertation approval form after the dissertation has been approved. The format of the dissertation must meet the published institute guidelines.
The candidate must submit the dissertation and the signed dissertation approval form to the Georgia Institute of Technology Office Graduate Studies and Research by the deadline published by the Institute. The deadline is typically 12-14 days before last day of classes. Check the official school calendar.
As mentioned above, your advisor is the chair of your dissertation defense committee. Your committee should be formed of at least five people. At least one faculty member must be from outside CoC (from another unit at Tech or an outsider, and should have a Ph.D.), but the majority must have some CoC faculty appointment.
Note: You only need to have three people on your committee at the time of your proposal, but it is recommended that you have all five members at that time. All members of your committee should be present for the defense; however, in hardship cases, measures such as conference calls can be used as well.
Advertising the defense
The Graduate Studies office asks that you post an announcement of the defense to the git.cc.general and git.announce newsgroups. This should be done at least fifteen (15) working days prior to the defense. The announcement should consist of the day/time/place of the defense, title, abstract, and a list of the committee members. Please provide an electronic copy of this announcement to the Ph.D. Coordinator in Student Services so that s/he may forward it to the GT Graduate Studies department.
