Seung Geol Choi

Hi, I am a postdoctoral researcher   under the direction of Jonathan Katz at University of Maryland. I am interested in Cryptography, Security, and Computational Complexity. I received my PhD from Columbia University   where I was advised by Tal Malkin and Moti Yung . I received my undergraduate and master's degree in Computer Science and Engineering from Seoul National University. Here is my CV.
