She has more than 30 years of experience in theoretical and computational chemistry. She develops new methods and algorithms for high performance computational chemistry as well as applying those techniques to both basic and applied research. Her current application interests are rare earth and heavy element chemistry, separations, catalysis, aerosol formation, cellulose degradation, and photochemistry. Much of her research interests involve large, collaborative efforts between scientists in multiple fields working together to solve difficult scientific challenges. She is a distinguished professor in the Chemistry Department of Iowa State University. Prior to joining Ames Laboratory, she worked at Pacific Northwest National Laboratory as the lead for the NWChem development group and the Visualization and User Services Group. She also worked at the Wright Patterson Air Force Base in technology transfer and training. She received her bachelor’s in chemistry, mathematics, and computer science from Minot State University and her doctorate in physical chemistry from Iowa State University.
He is a senior nuclear reactor physicist and a fellow in the Nuclear Science and Technology Directorate at Idaho National Laboratory (INL). He has extensive experience in reactor physics, criticality safety, depletion and spent fuel characterization, cross-section processing, and computer code verification and validation. He joined INL in 2010 from Oak Ridge National Laboratory to assume a leadership role in reactor physics methods and applications, supporting both the INL Advanced Test Reactor (ATR) and Transient Reactor Test Facility (TREAT). He is currently the principal investigator and research director for development and validation of a modeling and simulation capability for TREAT under the U.S. Department of Energy (DOE) Nuclear Energy Advanced Modeling and Simulation program (NEAMS). He also served as a technical lead for design, methods development, and validation for the conversion of ATR to Low Enriched Uranium (LEU) under the DOE Office of Material Management and Minimization. He is the primary developer of the NEWT and TRITON reactor physics computer codes released within the SCALE code system for nuclear analysis. He holds degrees in nuclear engineering from Texas A&M University and is a fellow of the American Nuclear Society (ANS). He has served as session organizer and chair for numerous technical sessions at national conferences. He has more than 100 publications in journals, conference proceedings, and national laboratory reports related to computational methods and applications in reactor physics, radiation transport, criticality safety and depletion methods for spent nuclear fuel.
