An oral presentation of the master's thesis is required. A decision on acceptance of the thesis will be made by the student's advisory committee after an oral examination is successfully completed. A decision on the acceptance of a written report based on problems in lieu of theses will be made by the student's advisory committee. Guidelines for thesis preparation are available from the department secretary. See also the graduate school requirements at www.gradschool.unt.edu.
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 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.
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 written and oral sections 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. Contact the Toulouse School of Graduate Studies or the program for current admission requirements, or see information posted on the graduate school web site at www.gradschool.unt.edu.
An entrance interview and proficiency examination are 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.
1. A written qualifying examination is taken after completion of the core curriculum courses over the contents of these courses. The departmental examination committee will schedule and administer the exam, usually in the summer semester.
2. Students have a total of two attempts to pass the written qualifying examination.
3. Students who pass the written qualifier are scheduled for the oral examination, which is to be conducted within one month of passing the written examination. The oral examination consists of a proposal by the student on how he/she would perform PhD research on a topic unrelated to their current field of research designated by the evaluation subcommittee. Students have a maximum of two attempts at the oral examination.
4. Upon passing the written and oral examination by the examination committee and major adviser, the applicant applies to the dean of the Toulouse School of Graduate Studies for admission to candidacy and may begin research.
This oral examination is primarily a defense of the dissertation, which must be submitted in final form to the final examination committee at least seven 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 and Engineering. Guidelines for dissertation preparation are available from the department secretary.
For the student who has not had previous graduate study, the approximate requirements follow.
