Research Interests

My research interests lie in quantum condensed matter theory. One major direction of my research is to understand and predict material properties (transport, magnetic, and optical) from the viewpoint of Berry phase and topology. In particular, I'm interested in topological phenomena arising from spin-orbit coupling and many-body interactions. These phenomena are often characterized by novel electromagnetic responses, which may be useful for applications in quantum electronics and quantum computing.
