Research

Programming Languages w/ Cormac Flanagan
I am part of the Slang research group.
I work on cooperability, an exciting property for concurrent programs.
We have a weekly reading group.

We organized the Workshop on Transitioning to Multicore (TMC 2011), as part of SPLASH in Portland, Oregon.

Real-Time Systems w/ Scott Brandt

I also run The What Is...? Graduate Seminar (TWIGS).

Background

My home is Seoul, Korea. My general interests include science fiction, philosophy, Russian literature, and Astor Piazzolla's music. I've picked up some other interests too: bike fixing, playing fiddle music, and tea. I know computers can be made to do much more than they can now, and that is one of my motivations for pursuing research in computer science. I started graduate school in September 2006, and finished in December 2011. I really enjoyed my time in Santa Cruz, but I've now moved to San Francisco. Stay tuned!
