Dr. Wendy A. Bohrson
Ph.D. 1993, University of California at Los Angeles
Current Interests, Projects and Research Students:
Wendy integrates investigations of the physics and chemistry
of magmas to understand how magma bodies evolve. By combining field, analytical, and
theoretical modeling studies, she documents the changes in magma
properties as melts rise from their mantle source regions (~100
km depth) to Earth's surface.
Bohrson received her Ph.D. from UCLA in 1993. From 1994-1998, she held a University of California Office of the President Postdoctoral Fellowship and a National Science Foundation Postdoctoral Fellowship, and was employed in the Department of Geological Sciences at the University of California, Santa Barbara as a researcher and lecturer.
At Central Washington University, Bohrson has been the Director of the Office of Undergraduate Research (2000-2003), and the Interim Director of Unviersity Research (2002-2003). She is currently the Director of the CWU Science Talent Expansion Program.

Teaching Interests and Schedule
Dr. Bohrson teaches undergraduate major course in Rocks and Minerals, as well as upper-level undergraduate/graduate level courses in Igneous Petrology, Volcanology, and Geochemistry. She also teaches graduate classes in her discipline and contributes to the core graduate classes, including research methods and field geology of the Pacfic Northwest.
