what are the maximum number of Phds a person is allowed to do?

Answer 1

PhD Course Requirements


The Doctor of Philosophy in Computer Science is, above all else, a degree of quality. Simply completing a number of graduate courses or years of study is not sufficient to receive the degree. The successful candidate must demonstrate a breadth of understanding in computer science and a depth of understanding in their chosen area(s) of emphasis.

Students must also show an ability to do creative research. Thus, each successful PhD candidate will produce a significant piece of original research presented in a written dissertation and defended in an oral examination. This work should be of such quality that one or more journal or conference articles can be derived from it.

* Completion of at least 90 credits of graduate course work beyond a BS-CS or at least 60 credits beyond a MS-CS with a minimum class grade of B and always maintain a 3.5 during their PhD career.
* 9 additional relevant credits for appropriate courses outside the department or for additional 7000-level CS courses beyond the 12 credits of 7000-level CS courses already required. The maximum credits listed in the table below indicate the maximum number of credits permitted for courses offered by other departments.
* CS 5950 or CS 6950 or CS7950 can be taken only with advisor's prior permission and only for 3 credits at a time. The maximum total number of credits allowed for CS 5950 plus CS 6950 plus CS7950 is 3 (with previous MS) or 6 (without previous MS).
* CS 6250 CANNOT be counted on the Program of Study.
* CS5200 is the same as the sequence of courses ECE6600 and ECE 7610. Students can include CS 5200 on their Program of Studies, or they can include ECE6600 and ECE 7610, but not both CS 5200 and one or both of those ECE courses. Students can use ECE7610 as a prerequisite to CS6200.
* Pass a set of written examinations and an oral examination showing depth and breadth of knowledge in computer science and their area(s) of emphasis. Students admitted to the PhD program with a master’s degree must complete the exam(s) by the end of their first year of matriculation. Students admitted to the PhD program without a master’s degree must complete the exam(s) by the end of their second year of matriculation.
* Successfully complete a research proposal.
* Successfully complete and defend a dissertation.

The research proposal and dissertation are to be the equivalent of 27 semester credits.

Table 7: Course and Credit Requirements for PhD degree. "Without MS" denotes students without a MS-CS degree, "with MS" denotes students already holding a MS-CS degree. Unless otherwise noted, a credit hour value denotes the number that must be included in the degree. No more and no less than this number may be included.

PhD without MS PhD with MS
7000-level Computer Science Credits 12 (minimum) 12 (minimum)
Credits awarded from MS 0 30 (maximum)
Seminar (CS7900) 2 2
Dissertation (CS7970) 27 27
Additional Relevant Courses 18 (maximum) 9 (maximum)
Total Credits (minimum) 90 90

Answer 2

None. You can study and get PhD as many times you want in different areas.

Answer 3

There is no limit. But it is of no use.
