Three researchers from the Department of Energy’s Oak Ridge National Laboratory (ORNL) have been elected fellows of the American Physical Society (APS).
 
Fellows of the APS are recognized for their exceptional contributions to the physics enterprise in outstanding research, applications and leadership in or service to physics and physics education. Each year, less than one half of 1% of the Society’s membership is recognized by their peers for election to the status of APS Fellow.
 
Hagen, task leader of the Nuclear Theory program in ORNL’s Physics Division, was cited by the APS Division of Nuclear Physics “for contributions to the development of coupled-cluster models in nuclear physics and his theoretical predictions for the structure of rare isotopes.”
 
Matsuda, neutron scattering scientist in the Spectroscopy Group of ORNL’s Neutron Sciences Directorate, was cited by the Division of Condensed Matter Physics “for important contributions to the study of spin-lattice effects in frustrated magnets and to the study of electronic phase separation and magnetic excitations in lightly-doped high-TC cuprate superconductors in using neutron scattering.”
 
Paranthaman, corporate fellow and leader of the Materials Chemistry Group in ORNL’s Chemical Sciences Division, was cited by the APS Forum on Industrial and Applied Physics “for distinguished contributions to the field of materials synthesis and characterization for high-temperature superconductors, solar cells, lithium ion batteries and additive manufacturing of magnetic materials.”
 
Paranthaman is a Distinguished UT-Battelle Inventor, 2016 ORNL Inventor of the Year and a UT-ORNL joint faculty member with the Bredesen Center for Interdisciplinary Research and Graduate Education. He is a fellow of several professional societies, including the National Academy of Inventors, MRS and AAAS, and has 42 patents and more than 400 journal publications with a Google scholar h-index of 62 related to superconductivity, energy storage and solar cells.
