Dr. Sai Mu joined the Materials Science and Technology Division of the Oak Ridge National Laboratory as a postdoc research associate in Oct, 2015; he received his Ph. D in the area of condensed matter physics, from the University of Nebraska-Lincoln in Dec, 2014. As a member of thrust 1, he is currently involved in the ab initio studies of the electric transport and thermal transport in EDDE alloys. His major role includes the ab initio study of the effect of chemical disorder, magnetism, and displacement fluctuation on the electric resistivity of the EDDE alloys. In addition, the lattice thermal conductivity, due to el-ph coupling, chemical disorder, and other effects, will be investigated.
