Yu He will join Yale as an assistant professor in the Department of Applied Physics starting fall of 2020. His research mainly utilizes light-matter interaction to investigate correlated electronic systems and other functional quantum materials. He focuses on dissecting novel materials’ microscopic degrees of freedom - electronic, lattice and spin - via angle-resolved photoemission spectroscopy, inelastic x-ray and neutron scattering techniques. To achieve a holistic view of material properties, complementary techniques such as electric transport, surface decoration and crystal synthesis are employed to characterize and manipulate material properties. Yu obtained his B.S. in Physics from University of Science and Technology of China (USTC), M.S. in Electrical Engineering and Ph.D. in Applied Physics from Stanford University. Prior to arriving at Yale, he worked as a Miller Research Fellow at the University of California at Berkeley.
