I am a Ph.D. candidate in the Department of Computer Science at Purdue University. My research interest lies in cryptography and relevant theoretical problems. In particular, I have been fascinated by exploring the intersection of graph theory and cryptography, focusing on the classical and post-quantum security analysis of Memory-Hard Functions and Proofs of Sequential Work. I am also drawn to analyzing preprocessing security of cryptographic primitives in multiple idealized models, including short Schnorr signatures and Key Encapsulation Mechanisms. I have been honored to be advised by Prof. Jeremiah Blocki since Spring 2019. Prior to joining Purdue, I completed my M.Sc in the Department of Mathematical Sciences at Seoul National University and B.Sc at POSTECH.
