Miaomiao (Mia) Jin is an assistant professor in the Ken and Mary Alice Lindquist Department of Nuclear Engineering. Jin earned her Ph.D. from the Department of Nuclear Science and Engineering at Massachusetts Institute of Technology in 2019, and bachelor's degree in nuclear engineering at University of Science and Technology of China in 2013. Prior to joining Penn State, she completed a postdoctoral appointment at Idaho National Laboratory in 2020. Jin’s research focuses on computation materials relevant to nuclear applications, including atomistic simulations of materials behavior under extreme environments, multiscale modeling to infer property evolution/degradation, and data-driven prediction of radiation-induced material response.
