(Voting Units:  Academic)

 

 

 

“Doctor of Philosophy Degree Program in Geophysics”

 

 

 

1. General Description of the Program

 

The faculty of the Department of Geological and Mining Engineering and Sciences (GMES) at Michigan Technological University seek to establish a Doctor of Philosophy program in Geophysics. Graduates of the program will have broad training in geophysics and develop expertise in one or more of the following specialties: earthquake seismology, exploration seismology, geomagnetism, and volcano seismology.

 

 

2. Rationale

 

The GMES department recently hired two new faculty members who have specialties in geophysics, bringing the total number of geophysics faculty to six (Suzanne J. Beske-Diehl, Jimmy F. Diehl, Wayne D. Pennington, Aleksey V. Smirnov, Roger Turpening, and Gregory P. Waite). While the department currently graduates PhD students with specialties in geophysics, their degrees are awarded in geology or geological engineering. These graduates are geophysicists by training, but their degree titles do not accurately reflect their expertise. In some cases, the lack of a Geophysics PhD program has been a deterrent for applicants or would-be applicants to the department. Having a PhD degree in geophysics is particularly important for enabling our new assistant professors to attract high-quality PhD students.

 

The GMES department has long had an undergraduate program in Applied Geophysics, and a Master of Science program in Geophysics. Both programs have traditions of successfully placing graduates in other graduate programs, or with positions in the public and private sectors. The new PhD program in Geophysics builds on the strengths of the existing geophysics programs. In addition to the Applied Geophysics B.S. and Geophysics M.S., the GMES department awards B.S., M.S., and PhD degrees in both Geology and Geological Engineering. We also offer graduate degrees in Mining Engineering. Our new Geophysics PhD program will provide continuity across all graduate programs within the GMES department.

 

 

3. Related programs

 

3.1. Related Programs at Michigan Tech

 

The programs most closely related to the new Geophysics PhD program are the Geological Engineering and Geology PhD programs offered through the GMES department. These programs have outlined specific criteria that have been used to assess their success: 1) upon graduation, PhD students in geology and geological engineering have demonstrated the ability to carry out an advanced and original research project, including its written and oral communication; 2) their projects have synthesized knowledge from different scientific disciplines; and 3) PhD students gain experience as research proposal writers. The department requires presentation and defense of a research proposal and students are expected to participate in the preparation and writing of proposals for internal and external funding. There are no specific coursework requirements for the PhD; the advisory committees design a program of study tailored to each student’s background and research interests. Additional courses may be added to the program of study based on the result of the comprehensive (qualifying) exam. Emphasis is placed on research and publication of research. The average student completes the PhD in 4-5 years.

 

3.2. Related Programs at Other Institutions

 

There are approximately 25 Geophysics PhD programs in the United States as of 2008 [1].  We conducted an informal survey of a subset of these programs in order to assure that our graduates will be competitive with those from other institutions. We found that many programs have requirements that are similar to those of our Geology and Geological Engineering programs. They generally require some combination of oral and/or written comprehensive examination, sometimes called a qualifying examination. Some programs (e.g., Caltech, Princeton) have specific coursework requirements with 45 or more credits, while other programs have no specific requirements. Instead, they allow their students’ committees to design course schedules tailored to students’ backgrounds and research interests. This flexibility is especially desirable for geophysics graduate programs. Most colleges and universities do not offer a B.S. degree in geophysics so geophysics graduate programs are likely to attract a large number of students with undergraduate degrees in physics, mathematics, or a related field, rather than geophysics.

 

3.3. Anticipated Enrollment

 

There are currently four PhD students who are being advised by geophysics faculty who would be affected by this new degree program. As the junior faculty members build their research programs, this number may increase to as many as 10.

 

 

4. Curriculum Design

 

Students entering geophysics graduate programs come from a variety of backgrounds. They are as likely to have bachelor degrees in physics or mathematics as geophysics or geology. Therefore it is up to the advisory committee to design curricula for students based on their experience and deficiencies.

 

As with the PhD programs in Geological Engineering, Mining Engineering, and Geology within the GMES department, no courses will be explicitly required for the PhD in Geophysics. Each student, in consultation with the thesis committee, will develop an appropriate program of study with courses that complement their research activities. A minimum of 30 semester credits beyond the master's degree or 60 semester credits past the bachelor's degree are required. Courses may be within the GMES department and in other departments. In addition, the committee may require additional courses following the comprehensive examination. There is no modern language requirement.

The comprehensive exam will be a written examination of fundamental and advanced topics in geophysics. The thesis committee chair will be responsible for soliciting the committee members for content and judging the exam.

 

4.2.2.   Research proposal

 

Following successful passage of the comprehensive exam, students will be required to present and defend a research proposal. The proposal is intended to provide focus for research. The presentation is open to the public. Following the presentation, the student has an opportunity to defend the plan before both a public audience and audience made up of only the advisory committee.

9. Planned Implementation Date

 

We would like to make this degree available as soon as possible (Fall 2010). One student who is close to graduation would be affected in the short term.

 

 

10. Core Geophysics Faculty

 

The GMES department has six geophysics faculty members including one Research Professor (R. Turpening). The curricula vitae of these faculty members are available online as Appendix A:

http://www.geo.mtu.edu/~gpwaite/GeophysicsPhD/AppendixA.pdf.

 

 

11. Affiliated Faculty

 

In addition to the six core geophysics faculty members, several other members of the GMES graduate faculty are likely to assist in educating the Geophysics PhD students. They are listed in the table below. The expertise of faculty members from other departments (e.g., Physics, Electrical Engineering, Mathematics, School of Technology) and other institutions will be sought as necessary on a case-by-case basis. In addition, the GMES department is conducting two faculty searches. We anticipate the new faculty members, who will have expertise in the related disciplines of Atmospheric Science and Geological Engineering, will provide additional assistance to train some of the Geophysics PhD students as well.

 

GMES faculty with research interests in fields closely related to geophysics.
