Lei joined the Hautier Group in Sep. 2023 as a postdoc research associate. Before that, he obtained his BS, MS and PhD all in Materials Science from Shanghai Jiao Tong University, Penn State and Georgia Tech. He also did an internship at Oak Ridge National Lab and a postdoc training at CMU. Lei has a broad interest in the role of defects on the ion transport, interfacial electrochemistries and other exotic properties. He is also curious about the link between continuum-level models and atomistic-level simulations. In the Hautier Group, he aims to figure out the relationship between the defects and the interfacial electrochemical properties. Outside the Lab, Lei likes many things that could make him forget about materials science for a while. Born in a city of Hubei Province near Yangtze River, he enjoys rainy days. His favorite time is an after-rain stroll in the misty forest or near a creek. His favorite material systems are simple oxide crystals (with imperfections, of course!) in fluorite and perovskite lattices, and rutiles recently.
