Yu He joins Yale as Assistant Professor in the Department of Applied Physics. His research mainly utilizes light-matter interaction to investigate functional quantum materials. He focuses on dissecting material’s microscopic behaviors - electronic, lattice and spin - via angle-resolved photoemission spectroscopy, inelastic x-ray and neutron scattering techniques. 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 the University of Science and Technology of China (USTC), and his M.S. in Electrical Engineering and his 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.
