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.

  • Studying carbon dioxide content in the atmosphere within caves
  • Studying the correlations between the composition of the geological formation and the CO2 levels
  • Understanding how much of the carbon dioxide produced in the cave environment adds to the CO2 levels in the outside atmosphere
