I am a research fellow at Korea Institute for Advanced Study. My mentor is Professor Young-Hoon Kiem. My area of interest is algebraic geometry. In particular, I am interested in foliations, moduli theory, and minimal model program.
Before coming to Korea, I was a Post-doctoral fellow at National Taiwan University under the supervision of Jungkai Alfred Chen, a Research Associate (Postdoc) at Imperial College London under the supervision of Paolo Cascini, and a Postdoctoral fellow at NCTS under the supervision of Jungkai Alfred Chen.
I obtained my Ph.D. at the University of Utah under the supervision of Christopher D. Hacon.
Here is a copy of my CV.
