The Ph.D. degree program, with interwoven components in lithospheric and hydrospheric science, is problem oriented rather than specialty oriented: this program is designed to produce scholars and practitioners capable of applying their training to achieve sound and pragmatic solutions to real problems in the earth sciences. Students in the doctoral program will normally spend a minimum of two years of formal course work, not including dissertation research.
To be considered for admission to the program, an applicant must meet Graduate School Requirements plus the following program requirements:
- Hold a master’s degree in one of the natural sciences, engineering, or mathematics or have equivalent experience.
- Have an appropriate background in aspects of the geosciences relevant the intended field of study.
- Submit scores from the Graduate Record Examination (General Test).
- Arrange to have at least three (3) letters of recommendation sent to the Graduate Coordinator of the Department of Geosciences.
Exceptional students without a M.S. degree may be considered for admission. A student who holds a master’s degree from UWM must formally reapply for admission to the Graduate School before continuing studies toward the Ph.D.
Course of Study
Doctoral students must earn 54 credits beyond the bachelor’s degree, of which 24 credits may be taken from formal course work completed as part of the master’s study. At least 21 graduate credits beyond the master’s degree must be earned in formal coursework.
Each student must prepare a formal Program of Study to be submitted to the Graduate School within the first semester in the program. Courses are selected in consultation with the student’s advisor with approval from the Doctoral Committee. Students are strongly advised to take courses from each of their committee members prior to taking the doctoral preliminary examination. For full time students, coursework should be completed within 4 semesters after admission to the Ph.D. program. In unusual situations, this timetable may be extended beyond 4 semesters. A timetable for coursework completion for part time students will be established on an individual basis.
The Graduate School requires satisfaction of a residency requirement. This involves completing at least 8 graduate credits in 2 consecutive semesters or 6 graduate credits in 3 consecutive semesters (exclusive of summer sessions) while in full doctoral status at UWM. In addition, at least half of the graduate credits required for the Ph.D. must be earned at UWM.
A working knowledge of computer programming, statistics, numerical methods, or GIS appropriate to the student’s field of study is required. Standards for this requirement will be established by the student’s Doctoral Committee. Undergraduate courses taken to meet this requirement do not apply to the course requirements for the Ph.D.
The membership of the Doctoral Committee will be established in the student’s first semester. The Committee must consist of the following: the doctoral student’s advisor as chair (or co-advisors as co-chairs); at least three additional graduate faculty members from the Geosciences Department; and at least one member from outside the student’s fields of specialization. The student is required to arrange a meeting with the Doctoral Committee at least once each year.
The student may request a change of advisor if another faculty member is available, willing, and able to assume that role. If this change involves a significant modification of the area of specialization or research, the student’s record will be reexamined to determine whether the student’s background is sufficient for the new specialty. If it is not, it may be necessary for the student to withdraw from the program and reapply in the new specialty. Normally such a change of direction will not be allowed once the dissertation proposal has been defended.
Doctoral Preliminary Examination
Advancement to dissertator status requires that students must pass a doctoral preliminary examination and then develop and successfully defend a dissertation proposal. The doctoral preliminary examination is administered in two parts: a set of written exams and a follow-up oral exam. The structure of the examination will be established by the student’s Doctoral Committee. It must be passed prior to the completion of 24 credits in the program and must demonstrate knowledge in the fields of geology and related sciences defined by the Doctoral Committee. The written and oral exams are taken after the residency requirement is fulfilled.
Subsequently, the student must present to the Doctoral Committee a written proposal in NSF format for her/his dissertation research. At a minimum, it should provide an overview of and approach to the problem being addressed, a budget, and appropriate bibliographic references. The dissertation proposal should be defended within one semester of completion of the preliminary exam. Students who successfully pass all three elements of the doctoral preliminary examination are admitted to doctoral dissertator status.
Annual Presentation of Results
Each dissertator is required to make a 30-minute presentation of research results at a Geosciences Colloquium each year. Dissertators also are required to make a 50-minute colloquium presentation of the results of the completed doctoral research prior to the dissertation defense.
The candidate must present a written dissertation reporting the results of independent, original research carried out under the direction of the major professor. Prior to a defense, the dissertation must be reviewed by a Reading Committee consisting of the major professor and at least two other members of the Doctoral Committee. Information regarding dissertation deadlines, preparation, and review of the dissertation is available from the Student Services Office of the Graduate School.
The student first will present research results in a colloquium. Then the dissertation must be orally defended before the entire Doctoral Committee. The defense may include questions related to any of the dissertator’s fields of study. If the dissertation is defended and the oral examination is passed to the satisfaction of a majority of the Doctoral Committee, the candidate is passed and recommended for the degree.
All degree requirements must be completed within ten years from the date of initial enrollment in the doctoral program.
