Christopher Cahill was born in Huntington, NY and grew up on an apple orchard in nearby Fort Salonga. His education includes a BS in Geochemistry from the State University of New York (SUNY) at Fredonia (1993) and a PhD in Chemistry from SUNY-Stony Brook (1999). He joined the faculty of GW in 2000 after a one-year post-doctoral position in the Environmental Mineralogy group at the University of Notre Dame. He is an expert in solid-state and materials chemistry with a particular emphasis on X-ray crystallography. His synthesis expertise includes high temperature techniques, as well as hydrothermal systems to produce novel hybrid materials of relevance to the nuclear fuel cycle. He has published over 150 peer reviewed papers in a range of areas related to the synthesis and structural characterization of materials and minerals. Current research areas include exploring the behavior of uranium and transuranic species under environmentally relevant conditions, as well as the synthesis of lanthanide containing sensor materials. Chris is the first physical scientist at GW to hold a joint appointment in the Elliott School of International Affairs, where he develops and delivers technical curricula targeting non-technical nuclear policy professionals. He is a recipient of the prestigious NSF CAREER Award (2004), a Bender Teaching Award (2005), a Fulbright Scholarship (2008) and the Trachtenberg Prize for Teaching (2013). He is a past President of The American Crystallographic Association (2014-2016), a member of the Cosmos Club and has held visiting researcher positions at the Carnegie Institution of Washington and Argonne National Laboratory. Most recently, he spent a sabbatical (2015-2016) as the American Institute of Physics State Department Science Fellow at the US State Department’s Office of Weapons of Mass Destruction Terrorism on the Nuclear Forensics Team. Chris served as Acting Director of the Institute for International Science and Technology Policy at GW from January to June 2018. He has since been elected Chair of the Chemistry Department and will assume that role in July 2019.
