ABOUT ME

I'm a second-year Physics PhD student at University of Washington in Seattle. I am intrigued by the strongly correlated physics in new quantum materials and artificial heterostructures. I work in Prof. Matthew Yankowitz's group and am learning the device fabrication and transport measurement of 2D materials. My current research mainly focuses on the transport study of magnetic proximity effect in graphene-based heterostructures.
