Degree Programs

The Department of Materials Science offers graduate programs leading to the following degrees:

Master's Degree Options

The applicant seeking a master's degree in materials science will plan a degree program with the assistance of the student's major professor and the advisory committee. A graduate major must present credit for at least 32 semester credit hours. The student must maintain a B average in all formal materials science courses.

Option 1, Master of Science, Thesis

The graduate credit requirement for the Master of Science degree is 32 semester hours chosen in the following manner.

1. Five of the following six materials science core courses (15 semester credit hours): MTSC 5100, 5200, 5300, 5400, 5500, 5600.

2. Nine semester credit hours may be chosen from materials science or related fields, as approved by the major professor and the advisory committee.

3. Six semester credit hours of MTSC 5950 (Thesis). Work for the master's thesis is comprised of independent and original studies that may be experimental, computational, tutorial, bibliographic, pedagogic or a combination of these. As part of these requirements, the student must present a formal written report which must be approved by the major professor and the advisory committee and filed in the graduate dean's office. Reports for MTSC 5950 must be submitted in a form prescribed by one of the common refereed materials science journals, such as the manuscript form of the American Institute of Physics (see AIP style manual, current edition).

4. Seminar in Materials Science and Engineering, MTSC 5870. A minimum of 2 semester credit hours.

Option 2, Master of Science, Non-Thesis Option (Problems in Lieu of Thesis)

The graduate credit requirement for the Master of Science degree is 36 semester hours chosen in the following manner.

1. Five of the following six materials science core courses: MTSC 5100, 5200, 5300, 5400, 5500, 5600.

Examinations

An entrance interview concerning fundamental materials science is required of all students. The results are used for advisory, placement and remedial purposes.

An oral presentation of the master's thesis is required. The thesis is accepted by the student's advisory committee after an oral examination is successfully completed. A written report concerning problems in lieu of thesis must be accepted by the student's advisory committee; oral presentation is optional.

Doctor of Philosophy

The Doctor of Philosophy degree represents the attainment of a high level of scholarship and achievement in independent research that culminates in the completion of a dissertation of original scientific merit. Hence, it cannot be prescribed in terms of a fixed semester credit hour requirement.

Course work and research amounting to the equivalent of two academic years beyond the master's degree or three years beyond the bachelor's degree may be considered the minimum.

Generally, the degree consists of 90 semester credit hours beyond the bachelor's degree or 60 semester credit hours beyond the master's degree, with 12 semester credit hours allocated for the dissertation.

It is expected that the candidate will have published at least one original research article in a refereed journal prior to graduation.

Admission to the Doctoral Program

Departmental admission to the doctoral program in materials science (as distinguished from admission to candidacy for the PhD program) requires a satisfactory score on the first part of the qualifying examination. This is normally taken after completion of the basic curriculum, after the second year. Enrollment in MTSC 6950 will not be allowed until the student has completed this requirement.

Examinations

An entrance interview is required of all graduate students in materials science, as described above under the master's examinations. The following examinations apply to the Doctor of Philosophy degree.

Qualifying Examination

1. The first part of the qualifying examination is taken after completion of the basic curriculum and consists of an examination over its contents. The departmental examination committee will schedule and administer the exam.

2. The second part of the qualifying examination consists of the student's oral presentation to the graduate advisory committee. The presentation will detail a proposed dissertation topic and will demonstrate familiarity with both laboratory equipment and the theoretical basis of the phenomena to be studied. Upon acceptance of the proposal by the student's advisory committee, the applicant applies to the dean of the Toulouse School of Graduate Studies for admission to candidacy and may begin research.

Final Examination

This oral examination is primarily a defense of the dissertation, which must be submitted in final form to the final examination committee at least 30 days prior to the scheduled oral examination. At least one final examination committee member must be from a department other than the Department of Materials Science.
