Anne Sheehan Group
My research involves the use of geophysical methods, primarily seismology, but also including geodesy and electromagnetic methods, to understand mountain belts, subduction zones, and earthquakes. I am interested in the properties of the Earth’s crust and mantle, the nature of lithospheric deformation, and the causes and consequences of induced seismicity. My group’s field based projects include broadband and short period seismometer deployments, ocean bottom seismic and seafloor pressure gauge measurements, magnetotellurics, and geodesy.

Geoscience Scholarships for Undergraduates
Graduate Student Research Assistantships at the University of Colorado Boulder
Qualified students are encouraged to apply for graduate student research assistantships in the geophysics group of the Department of Geological Sciences at the University of Colorado. Students are expected to be self starters and able to work independently. Students interested in the Ph.D. program are given higher consideration for funding (M.S. is not required for entry to Ph.D. program). Students who apply for external fellowships such as the NSF Graduate Research Fellowship are given higher consideration. Our acceptance rate for the graduate program in Geological Sciences is around 15%. Entering graduate students typically have GPA of 3.4 or higher, excellent GRE scores, research experience, and strong reference letters.
Admissions information is available at www.colorado.edu/geologicalsciences (click on Student Info)
Completed applications for Fall 2020 are due on December 1, 2019.
For information about the Department and the University of Colorado, see our Web site: www.colorado.edu/GeolSci.
Prospective students are encouraged to apply for external fellowships such as:
- National Science Foundation Graduate Fellowships
- National Defense Science and Engineering Graduate Fellowship
- National Physical Science Consortium Graduate Fellowships
- Hertz Foundation Graduate Fellowship
- Science, Mathematics, And Research for Transformation (SMART) Defense Scholarship
