I am a CMC fellow (Postdoc) at Korea Institute for Advanced Study. Previously, I was a postdoc at Academia Sinica. I received my PhD in Department of Mathematics at the University of Utah in May 2022 supervised by Y.P. Lee. My research interests are in algebraic geometry, enumerative geometry, mean field equation, and related topics. Here is my CV.
