Assistant Professor Liang Qi

Liang Qi joined the Department of Materials Science and Engineering as an Assistant Professor in Winter 2015. Qi studied Materials Science and Engineering at Tsinghua University in China. He earned his master's degree at Ohio State University and doctoral degree of computational materials science at University of Pennsylvania. He continued his postdoctoral research at UPenn and Massachusetts Institute of Technology. During these times, his research focused on modeling and simulation of catalysis/electrocatalysis in fuel cells and nanostructured materials in collaboration with in-situ TEM characterizations [1,2]. Most recently, he worked as an assistant project scientist at University of California, Berkeley, where he performed first-principles and mesoscale simulations to study the deformation mechanisms and microstructures of advanced metallic alloys, and the materials chemistry related to nuclear fuels. There he found the intrinsic ductility of bcc refractory metals is determined by the symmetry-related electronic structure that can be tuned by alloying [3]. He also collaborated with experimentalists and found that the profound strengthening effect of Ti from oxygen impurities is due to the interaction of oxygen interstitial solutes with the core of mobile screw dislocations [4].


At U-M, Qi will continue studies on computational materials sciences by applying theoretical and computational tools, including first-principles calculations, atomistic simulations and multiscale modeling. His research interests are quantitative understanding of the intrinsic electronic/atomistic mechanisms for the mechanical deformation, phase transformation and chemical stabilities of structural and functional materials. By working with the outstanding students, researchers and faculty at U-M, he plans to integrate these electronic/atomistic results with multiscale simulations and experimental investigations in order to design materials with improved mechanical performance and chemical stabilities.
