B.A., Geology, Whitman College, 1996
M.S., Earth and Planetary Sciences, University of New Mexico, 1999
Ph.D., Earth and Environmental Sciences, Lehigh University, 2008
TEACHING AND RESEARCH AREAS:
My teaching and research interests include the fields of geomorphology, active tectonics, geodynamics, paleoseismology, paleoclimatology, and biogeomorphology. I approach research problems in a field-based, process-oriented, multidisciplinary manner. My research addresses questions such as:
- How do landscapes respond to tectonic and climatic forcing, and are there distinct topographic, erosional, stratigraphic, and bio-genetic signatures of these forces?
- How do human modifications of the landscape compare in magnitude to pre-human conditions?
- What conspiracy of geologic, seismologic, and climatic factors is important to the initiation of large, deep-seated bedrock landslides? Within a given region is the timing of landslide movement clustered or scattered?
Dr. Wegmann teaches classes in introductory and advanced Geomorphology, Earth Surface Processes, Active Tectonics, and Field Geology.
I am actively recruiting motivated graduate and undergraduate students who are interested in conducting fluvial, tectonic, and anthropogenic-related geomorphology thesis research projects.
