Dr. Cheng Sun is a staff scientist working in Materials and Fuels Complex at Idaho National Laboratory. His research areas are focused on mechanistic understanding of materials performance under extreme environments, with emphasis on the manufacturing-microstructure-mechanical property relationships of materials under neutron/ion irradiation. The materials of interest include advanced stainless steels, nickel-based superalloys, metallic fuels, etc. His primary area of experimental expertise includes advanced manufacturing of nuclear structural materials, electron microscopy and small-scale mechanical testing. He holds a Ph.D. in materials science and engineering from Texas A&M University in 2013, and was awarded as the very first Russell L. Heath distinguished postdoc fellow at Idaho National Laboratory in 2016. Before coming to INL, Dr. Sun was a G.T. Seaborg Institute Postdoctoral Fellow at Los Alamos National Laboratory, where he pursued research on radiation-induced solute redistribution in nuclear structural materials. He has worked on multiple DOE projects, including the Nuclear Energy University Program (NEUP), Nuclear Energy Enabling Technology (NEET), and Laboratory Directed Research and Development (LDRD) projects.
