Cheol-Hwan Park got his bachelor’s degree in 2000 from the department of physics, Seoul National University. He studied first-principles electronic structure methods during his doctoral study in the physics department of UC Berkeley where he got the PhD in 2009. He did his postdoc study in the materials department in Oxford University and in BOSCH research center in Cambridge, USA before joining the physics department of Seoul National University as a faculty member in Fall 2012. Cheol-Hwan Park is interested in investigating the interplay in real materials between charge, spin, orbital and photonic degrees of freedom from first-principles calculations.
