About me

I am a Ph.D. candidate advised by Prof. Jung Hee Cheon in the Department of Mathematical Sciences at Seoul National University (SNU). My major research topics are homomorphic encryption and lattice-based cryptography, but I am broadly interested in all aspects of cryptography and mathematical problems derived from them.

I received my Bachelor’s degree with Highest Honors from Mathematical Sciences at SNU in 2015.
