I am an Assistant Professor in the Department of Computer Science and Engineering at Seoul National University. My research interests are in Cryptography and Privacy. Recently, I have been working on homomorphic encryption and multi-party computation. I am also interested in building and implementing cryptographic protocols to solve the privacy issues in machine learning.
Before joining Seoul National University, I was a senior researcher in Cryptography and Privacy Research Group at Microsoft Research Redmond, managed by Kristin Lauter, from 2019 to 2020. Prior to that, I was a postdoctoral researcher at UC San Diego, under the supervision of Sicun Gao. I obtained my PhD in Mathematical Sciences at Seoul National University in 2018. My advisor was Jung Hee Cheon.
I am always looking for motivated students with backgrounds in computer science and mathematics. Our lab also has summer/winter internship programs to provide undergraduate students with research experience in the field of cryptography.
