(Brief Biographical Sketch)

Chris Klepper (Ph.D. 1985, UT-Austin) is a fusion energy researcher, plasma technologist and fusion diagnostics expert, with over 30 year of experience in both national laboratory and private sector R&D environments.  Has worked extensively in the environment of international fusion energy collaborations, leading several US Department of Energy projects while on long-term assignment in France and in the UK. Has also led projects for other US government agencies, including the National Science Foundation, the National Institute of Health, the Domestic Nuclear Detection Agency and the Department of Commerce.  Some of these projects were developed and carried out in collaboration with US industries, including Caterpillar Inc. and Zimmer Biomet. Currently, serving as Scientific Coordinator for international collaboration Experiments aimed to understand the relative contribution of the main chamber to impurity sources in the all-tungsten wall of the WEST super-conducting fusion energy device at Cadarache, France; also as Principal Scientist for the ITER Diagnostic Residual Gas Analyzer, whose Design and Manufacturing is the responsibility of the US Domestic Agency. He is the US Member in the ITPA TG on Diagnostics. Senior Member of the IEEE since 2005. Member of the APS and alumnus of Sigma Pi Sigma and Phi Beta Kappa.
