Biography

Evelynn Mitchell, Ph.D., earned her doctorate from the Environmental Science and Engineering program at The University of Texas at San Antonio. Mitchell taught physics at the University of the Incarnate Word prior to pursuing her Ph.D. She also gained experience in engineering and applied physics working as a manufacturing engineer at Sony Semiconductor from 2000 to 2003.

Mitchell focused on studying the Edwards Aquifer in her dissertation research, in which she used a combination of hydrogeology and geophysical skills to determine specific storage values using the compression of earthquake waves. She has also performed geophysics research using seismic and resistivity applications to look at the underlying geology and water table in the Texas Hill Country and in Jalisco, Mexico.

As a professor at St. Mary’s University, Mitchell has worked with students in studying carbon dioxide levels in local caves using ground penetrating radar to detect voids, and using electrical resistivity to examine subsurface locations. She started the University’s Community Garden, was Chair of the Sustainability Committee for three years, and has served as the St. Mary’s University representative on the West Side Creeks Oversight Committee, which drew on her background in hydrogeology. Mitchell has also presented her research internationally.
