Current Research Interests

I’m interested in classical and quantum gravity. One of my research topics is on dynamical behaviors of semi-classical black objects, where sometimes I used numerical techniques. The other one is on Euclidean quantum gravity, including the no-boundary wave function and various instantons. From these topics, I want to investigate (1) the information loss problem of black holes, (2) implications from quantum cosmology to physical cosmology, and (3) observational consequences from strong gravitational dynamics.

I came from Korea. Apart from research, I like books, including philosophy, history, culture, etc. Although my Chinese is poor yet, if it is possible, I want to increase my Chinese skill to read books those are written by Chinese. I like to play piano, especially contemporary Christian music. I like baseball, but not for playing but for watching. I like coffee and I am a heavy coffee drinker.
