Roger Kapsimalis leads the Process and Materials Characterization Group within the Nuclear Nonproliferation Division at ORNL. The group functions as a premier research organization at the lab, leveraging advanced scientific resources to further the fundamental science which underpins our national nonproliferation capabilities. In doing so, the group serves multiple facets of the US government for the timely, actionable assessment of fuel cycle materials.
Since joining the lab, Roger’s research has focused on the development and application of nondestructive micro-analytical techniques for the advanced characterization of actinide and non-actinide materials in support of the US Government’s nonproliferation objectives. Roger currently supports the community as principal investigator of multiple DOE NNSA research initiatives and leads efforts to operationalize the structural, chemical, and isotopic analysis capabilities of the laboratory for several government entities. In addition to his role at ORNL, Roger holds an appointment at The University of Texas at Austin as a Research Fellow and is an Intelligence Officer in the US Navy Reserves. He received his Ph.D. in Nuclear Engineering and a B.S. in Physics from The University of Texas.
