I'm an L. E. Dickson Instructor at the University of Chicago, Department of Mathematics. I obtained my PhD in mathematics from Stanford University under the supervision of Prof. Richard Schoen. Before going to Stanford, I was an undergraduate math major at the National Taiwan University (NTU).

My research interests are partial differential equations, differential geometry and geometric measure theory.
