Welcome to my webpage!
I am a Research Scientist at Google Brain. In my previous life, I was a theoretical high energy physicist working on topics in String Theory. I've held postdoctoral positions at Rutgers and Stony Brook University. My list of publications can can be found on Google Scholar.
I have earned my Ph.D. in high energy theoretical physics from MIT. My thesis is available online here. Before that, I've earned my B.S. in physics from Seoul National University.
The main purpose of this site is to post notes and presentations. A lot of them are not original and are based on already well-known facts, reorganized for my own convenience. Some of them are based on my own work.
