CV [link]

Previously, I was a Research Fellow/KIAS Assistant Professor (mentor: Jun-Muk Hwang) at KIAS from 2014 to 2018. I obtained my Ph.D from KAIST (advisor: Sijong Kwak) in 2014.
Please do not confuse me with Jinhyun Park, a professor of KAIST. My first name has one more letter 'g' at the end.

Research Interests
Algebraic Geometry
1. Positivity of divisors - Seshadri constants and Okounkov bodies
2. Projective geometry - Castelnuovo-Mumford regularity and secant varieties
3. Birational geometry - singularities of pairs, log Fano varieties, and Mori dream spaces/Cox rings
