Interests and Expertise

Dr. Christopher Gellasch is a geologist with a focus on groundwater (hydrogeology) and water quality. He returns to EMU after more than 20 years serving as a U.S. Army Environmental Science and Engineering Officer. His previous academic experience includes serving as an assistant professor at the U.S. Military Academy in West Point, NY and the Uniformed Services University of the Health Sciences in Bethesda, MD. His research combines aspects of hydrogeology and environmental engineering to determine the most likely pathways for chemical and biological contaminants to migrate through the subsurface and impact either public supply wells or surface water bodies.
