I obtained my Ph.D from KAIST, where my advisor was Sijong Kwak.
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
