I am an assistant professor in Computer Science and Engineering at College of Computing in Sungkyunkwan University. I was a postdoctoral researcher at SSLab in Georgia Tech, working with Taesoo Kim. I earned my Ph.D. in Computer Science (CS) from Stony Brook University (adviser: Michalis Polychronakis). I received the M.Sc. degree in Information Security from Korea University, working at the Digital Forensics Lab (DFRC) with Sangjin Lee. I studied computer science in the University of Texas at Austin as an exchange student. I also had worked for Samsung SDS and Shinhan bank in a security team. I am fortunate to have a variety of interesting experiences from both industrial and academic sides in the security field, thanks to the great people who led me.

With the Internet of Things, security matters everywhere by getting more connected each other ever. So I wanted to make this space reserved for writing down stuff (security findings, knowledge I often forget, what I have done for fun and so on). I like dealing with practical security which impacts on human’s life, based upon theory.
