Mary Leech, Professor of Geosciences
Mary Leech, a member of the Cherokee nation, began her college career at San Jose State University, where she graduated with a BS in Geology in 1994. She then attended graduate school at Stanford University. In 1999, she finished her studies for her PhD in Geological and Environmental Studies. During her time at Stanford, she held a National Science Foundation Minority Graduate Fellowship. Since her time as an NSF fellow, she has received multiple grants for funding from the foundation.
After her graduation from Stanford, Dr. Leech was an NSF International Research Fellow from 1999 to 2001. She began her fellowship at the University of London and then ended the fellowship at Stanford University. Once her fellowship was complete, she went to the University of California, Santa Barbara as a University of California’s Postdoctoral Fellow. In 2002, she began her professional experience as a lecturer at San Francisco State University while a Research Associate at Stanford University. In 2005, she began her present position at San Francisco State University as an Assistant Professor in the Department of Geosciences.
Dr. Mary Leech has traveled to and studied a variety of geologic features in numerous countries. Her field research has brought her to Tibet, the Indian Himalayas, China, Norway, Russia, Kazakhstan, and Great Britain. Her current research interests include studying structural geology and tectonics, geochemistry, geochronology, and igneous and metamorphic petrology. Dr. Leech’s ongoing work in the Himalaya and southern Tibet is being funded by the NSF CAREER Grant. Dr. Leech and her colleagues were also awarded NSF Major Research Instrumentation funding to purchase a field emission scanning electronmicroscope, which will be beneficial to students and faculty in their studies of chemistry, the geosciences, biology, physics, and engineering.
