Mechanical Engineering, PhD


Cullen College of Engineering  > Department of Mechanical Engineering  > Mechanical Engineering, PhD

The Doctor of Philosophy (Ph.D.) Program in Mechanical Engineering provides our students with an educational experience grounded in the
 engineering sciences and focused on producing a professional capable of systematically applying those sciences to solve real-world problems.
Our program encompasses advanced study and research in the areas of applied mechanics, control of dynamical systems, materials science,
thermal and fluid sciences, and biomedical engineering. The Ph.D. is the highest degree granted by the University and its possession signifies
that the holder has demonstrated the ability to perform original research. The student’s principal objective is to produce a dissertation that can be
considered a significant contribution to the field of knowledge in mechanical engineering. Our standard Ph.D. program assumes a completed M.S.
degree prior to admission. Our Direct Admit program allows the exceptional student to be admitted to doctoral candidacy without a completed M.S.
degree.

For more information, please visit the Doctor of Philosophy page.

Admission Requirements


To be admitted for doctoral studies, a student must have an exemplary scholastic record which includes:

  • an MS degree (standard admission) or a BS degree (direct-admit program) in Mechanical Engineer­ing or in a related field, preferably from an accredited engineering program.
  • three letters of rec­ommendation attesting to the student’s capacity to perform in the classroom and in a research capacity.  A minimum of two letters should be from tenure-track faculty members who have observed the academic performance of the applicant.  
  • a Statement of Purpose that is consistent with the current research areas within the Department.  An “Application for Financial Aid and Statement of Purpose” form is available on the Application section of this website.  It allows the applicant to specify areas of interest and academic goals, and it provides guidance regarding the issues we would like to see addressed in the statement of purpose.
  • a minimum score of 79 on the internet-based TOEFL exami­na­tion for students whose native lan­guage is not English.
  • a grade point average that demonstrates the potential to perform at the level of 3.40 or better in MECE graduate courses.
  • The GRE test score is waived for the Mechanical Engineering Ph.D. admissions.

Qualifying and Dissertation Examinations


A comprehensive qualifying examination is required early in the degree program, and a dissertation examination is required at the end.

More on Requirements


All PhD candidates must have at least one peer- reviewed (archival) journal paper accepted prior to his/her dissertation oral defense. This paper must be based on the student’s dissertation research at the University of Houston.

Breadth Requirement

Two courses with content outside of the research concentration area are required to insure a minimum academic breadth in the program.  The courses can be in MECE, and suitable courses in the Colleges of Engineering and Natural Sciences. The suitability of courses for the breadth require­ment is determined by petition to the Direc­tor of Graduate Studies.  This petition should be filed well in advance of the dissertation defense.

Comprehensive Qualifying Examination

This oral examination determines whether a student has mastered, and can integrate and apply, the knowledge gained in courses.  The student should set aside a period of time to prepare for the examination by reviewing course material and reflecting on how this information can be integrated to solve problems.

To stand for the PhD comprehensive examination, a student must have a grade point average of 3.40 or higher on a minimum of 12 UH graduate hours (4 classes) and no more than the first 21 UH graduate hours (7 classes).

The examination should be scheduled as soon the accumulation of relevant course work allows. For a student with an MS from another university, the exam should be attempted no later than 18 months after study towards the PhD begins.  For students who complete the MS here and for students who petition into the direct-admit program, the exam should be attempted within 12 months of the change of program.

The examination committee is set by the Director of Graduate Studies in consultation with the Mechanical Engineering core research
 groups (Controls, Materials, Mechanics, Thermo-Fluids) and the dissertation advisor. Click here for more information about the
general and transitional qualifying exam guidelines.  Some qualifying exam guidelines will vary by group. Please review the table

Dissertation Examination

A dissertation committee should be formed by the advisor, with the approval of the Director of Graduate Studies, during the semester
in which the student passes the comprehensive qualifying examination. This committee consists of at least four members of the
MECE Department including the advisor, and at least one member from outside the Department.

Department/Program Academic Policies


Residency

The College requires a minimum of one academic year (two long semesters) of full-time enrollment at the PhD level.

Ninety-nine Hour Rule

The student is cautioned to be aware of the scheduling involved in meeting these requirements.  University regulations require that a student who has accumulated more than 99 hours at the PhD level be charged out-of-state tuition for the hours in excess of 99.  This tuition rate applies to Texas residents as well as true out-of-state students.

Students requiring Doctoral Research and Dissertation hours should be advised of the following:

Doctoral Research and Dissertation. Doctoral Dissertation hours should be assigned an S or U grade which is changed to a letter grade after successful completion of the dissertation. An S or U grade must be assigned to every dissertation course until the dissertation is successfully completed (defended and submitted). A final letter grade via grade change request will be assigned to the required number of dissertation hours once the student has successfully completed the dissertation (defended and submitted). In case a student registers for dissertation hours over and above the nine hours that are required, these additional hours will remain as S or U on the student’s transcript. This is a Graduate School directive and aimed at avoiding grade inflation.

Dissertation hours (8x99) for a PhD degree are restricted to 12 hours. PhD students must take at least 30 hours of research and dissertation. Any additional hours should be registered as Doctoral Research 8x98 to complete the research credit hours requirement. Doctoral Dissertation hours should be assigned an S or U grade which is changed to a letter grade after successful completion of the dissertation. If a student is not done after registering required number of Doctoral Research and Dissertation hours, additional hours should be registered as Doctoral Research which are graded on S/U basis. In the event a student registers for extra Dissertation hours, these hours will be left as S or U. It is not necessary to assign the same grade to all the hours while completing S or U grade.
