Postdoctoral Research Associate - Thermal Transport of Actinide Materials
Research Areas: High Pressure Physics of actinides; Thermophysical Properties of Nuclear Fuel Materials ; Three omega thermal conductivity
Biography: Dr. Keshav Shrestha is a postdoctoral physicist who joined Idaho National Laboratory in 2015. He received his Ph.D. in condensed matter physics from Texas Center for Superconductivity at the University of Houston (TCSUH) in 2015. His research interests focus on the understanding of electrical and thermal transports, magnetic, and thermodynamic properties of various strongly correlated materials under extreme conditions, such as very low temperature, very high magnetic field, and very high physical pressure. Recently, his work includes developing the 3ω (3-omega) thermal conductivity measurement technique for actinide materials at ambient and under high pressure. He works in collaboration with other national laboratories and research institutes, such as pulsed magnetic field facility in Los Alamos National Laboratory, dc national high magnetic field facility in Tallahassee, Advanced Photon Source in Argonne National Laboratory, and Texas Center for Superconductivity.
