CV [link]

Previously, I was an Assistant Professor at Sogang University (March 2019 - February 2022) and a Research Fellow/Assistant Professor/CMC Fellow at KIAS (September 2014 - February 2019), where my mentor was Prof. Jun-Muk Hwang. I obtained my Ph.D from KAIST in August, 2014 under the supervision of Prof. Sijong Kwak.

I'm Jinhyung Park(박진형) not Jinhyun Park(박진현). There is an extra "g" at the end of my name. We are both algebraic geometers in the same department, but our research interests are different.
