About me

I am an Assistant Professor at College of AI Convergence, Dongguk University, Seoul, South Korea.

Previously, I was a Principal Engineer (Security and Cryptography) in Software Solutions and Algorithms Group at Western Digital, Milpitas, from Dec 2020 to Feb 2023.

I received my BS and PhD degrees in Mathematical Sciences from Seoul National University in 2013 and 2020, respectively. My thesis advisor was Prof. Jung Hee Cheon. I had been a Postdoctoral Researcher at IMDARC, Seoul National University, until Dec 2020.

My research interest is on several cryptographic primitives including Fully Homomorphic Encryption, Verifiable Computing, zk-SNARK, Multiparty Computation, and Lattice-based Cryptography, specifically aimed at improving their cost for practical applications.
More broadly, I am interested in developing theoretical results of cryptography and mathematics into solutions for real-world problems.
