About

I am a Ph.D. student in Computer Science at Brown University where I am advised by Prof. Anna Lysyanskaya. My main research area is Cryptography. Recently, I have been focusing on lattice-based cryptography and the management of digital credentials.

Before enrolling at Brown, I obtained an M.S. and a B.S. in Computer Science from Kennesaw State University. During my master's program, I was advised by Prof. Junggab Son.
