Welcome!

Our group works on novel physical phenomena in nanoscale devices and heterostructures arising from complex interactions such as spin-orbit coupling and exchange interaction at the interfaces. The phenomena we are interested in include the topological spin Seebeck effect in topological insulator/magnetic insulator heterostructures, quantum anomalous Hall effect in graphene and topological insulator surface states, spin current transport in ferro-, ferri-, and antiferro-magnetic insulators. We closely collaborate with other researchers in the DOE-funded  Energy Frontier Research Center (EFRC) on Spins and Heat in Nanoscale Electronic Systems (SHINES).
