个人简介

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 postdoctoral 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 100 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 species under environmentally relevant conditions as well as the synthesis of lanthanide containing sensor materials. He also maintains a joint appointment in GW’s Elliott School of International Affairs where he develops 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 the current Vice President of The American Crystallographic Association, a member of the Cosmos Club and has held visiting researcher positions at the Carnegie Institution of Washington and Argonne National Laboratory.

Hybrid materials, f-element chemistry, Nuclear fuel cycle, X-ray crystallography, and Luminescent materials

Hybrid materials (metal-organic frameworks and coordination polymers) find application in areas as diverse as gas storage, rad-waste immobilization, micro-electronics and catalysis. Those containing lanthanide (Ln) or actinide (An) compositions (aka the ‘f-elements’) are of particular importance to the nuclear fuel cycle and related environmental issues. Further, Ln elements see application in areas from medical imaging to magnetic materials and sensing devices. Synthetic routes for producing these materials often include soft-chemical or molecular design approaches. Soluble molecular precursors or even dense phase minerals provide the structural building units that are induced to assemble and link about organic ‘templates’ under hydro- or solvothermal conditions. Investigation of the properties of these (and other) types of materials is closely related to an understanding of their crystal structures. A major focus of our group is thus the X-ray structural characterization of both novel and naturally occurring solid-state compounds. Studies of this type make use of traditional in-house diffraction equipment, as well as the intense synchrotron x-ray sources at Brookhaven and Argonne National Laboratories.
