Benjamin J Drenth, Ph.D.

Biography

Ben Drenth is a Research Geophysicist in the Crustal Geophysics and Geochemistry Science Center in Denver, Colorado. His research is focused on the interpretation of gravity and magnetic geophysical data, in conjunction with other types of geophysical data and geologic information, to address 3D geologic mapping problems at a variety of scales. He specializes in interpretation in challenging physical and geologic environments, such as high-relief terrain and areas where the rocks of interest are concealed. USGS areas of focus include the National Cooperative Geologic Mapping and Mineral Resource Programs. He received a PhD in geophysics from the University of Oklahoma in 2009, a MS in geophysics from the University of Texas at El Paso in 2005, and a BS in geological engineering from Michigan Technological University in 2003.
