Professor Xiaodong Cui got his B.S. in physics at University of Science and Technology of China and PhD at Arizona State University. After his PhD, he did a joint postdoctoral research at Columbia University and IBM. He has been working at Physics department, University of Hong Kong since 2004. 

Professor Cui's research interests and experiences cover various subjects on spin and valley physics in semiconductors. Recently his research group conducted several pioneering experiments on optical properties of atomically thin 2D crystals in aspects of spin and valley physics.
