Di Xiao is a renowned theorist in the field of quantum materials. In particular, he is a pioneer in the fields of quantum valleytronics, two-dimensional (2D) van der Waals magnets, and the application of novel Berry phase effects in 2D quantum materials. Di is a prestigious Simons Fellow and his work is very highly cited (over 40,000 citations), earning him the honor of being named a Thomson Reuters Highly Cited Researcher every year since 2017, a distinction only the top 1% of the researchers have in the field. Dr Xiao is a joint appointee with Pacific Northwest National Laboratory (PNNL) and University of Washington.

• Condensed matter physics
• Quantum computing.

Xiao develops novel ways to probe and control magnetism in van der Waals materials. He investigates novel phenomena, including transport and optical signatures of topological phases and heterostructure engineering of novel quantum states.
