Biography:
Dr. Yongfeng Zhang is currently a staff scientist at Idaho National Laboratory. He leads the Computational Microstructure Science group in the Fuels Modelling and Simulation Department, which leads the development of the mesoscale fuel performance modeling code MARMOT. He has served as the PIs of multiple work packages under the Department of Energy NEAMS program and the USHPRR programs and two laboratory directed research & development (LDRD) projects, and co-PIs of many other projects. Dr. Zhang graduated from Rensselaer Polytechnic Institute with a PhD degree in Mechanical Engineering, Aug. 2009, and joined INL after that. His research focuses on atomistic to mesoscale modelling and simulation of the concurrent evolution of microstructure and properties in materials used in nuclear environments combining high temperature, stress, irradiation and corrosive species. The phenomena of interest include radiation damage, swelling, phase transformation, corrosion and degradation in mechanical and thermal properties in various fuels, claddings, and structural materials. Dr. Zhang has authored or co-authored over 40 peer-reviewed journal publications and delivered over 30 conference presentations. He is the recipient of the Laboratory Director’s Award for Leadership in 2017.
