Biography:

Lingfeng He is a distinguished scientist and HRMC group leader in Advanced Characterization Department at Idaho National Laboratory. Dr. He received his PhD degree in materials science at Chinese Academy of Sciences in China in 2009, and then worked as postdoctoral research associate and assistant scientist at Nagaoka University of Technology, Japan, and the University of Wisconsin-Madison before joined INL in 2014.  Dr. He is interested in materials behavior under extreme environments, with a focus on environmental degradation of materials in nuclear power systems. Dr. He's goal is to understand how the processing and radiation/corrosion environments change the microstructure of materials and its effects on the mechanical, corrosion and thermal properties of materials. He probed these interactions by virtue of cutting-edge electron microscopy and spatially resolved spectroscopy techniques. His current research projects include microstructure characterization of as-fabricated and irradiated nuclear fuels (oxide fuels, nitride fuels, silicide fuels, and metallic fuels) as well as advanced structural materials (ceramics, steels and nickel based alloys). Dr.  He services as the PI/Co-PI for Basic Energy Sciences (BES) Core Program, Energy Frontier Research Centers (EFRCs), International Nuclear Energy Research Initiative (I-NERI) project, Laboratory Directed Research and Development (LDRD) projects, Nuclear Energy University Program (NEUP) project, Nuclear Science User Facility (NSUF) Rapid Turnaround Experiments (RTEs) and SBIR/STTR. Dr. He has authored/co-authored 105 peer-reviewed journal publications, with an H-index of 26, cited over 1700 times (Web of Science), 145 technical presentations (including 34 invited) and held 5 patents. He is a reviewer of 44 journals, e.g. Acta Materialia, Corrosion Science, Journal of the American Ceramic Society, Journal of Nuclear Materials, PNAS. He is also an active reviewer for proposals from US Department of Energy (DOE), Office of Nuclear Energy, NEUP, NSUF, DOE Office of Science, SBIR/STTR, LDRD at Idaho National Laboratory. He has been a mentor for 5 postdoctoral researchers, 3 graduate students and 6 summer intern students.​
