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!

Stuff to do in Santa Cruz!

• Climb the moon rocks in the Bonny Doon mountains
• Go tidepooling along the rocks next to Natural Bridges Beach
• Take the train up to Felton with hundreds of fellow cyclists and bike down Highway 9!
• Listen to friends play music at a tea house
• Enjoy a soak at the local spa
• Bike up to Bonny Doon -- a challenging ride! Try going up Icecream Grade or Smith Grade.
• Learn some acro yoga
• Watch shooting stars lying down at the beach
• Buy fresh organic food at the Farmers Market
• Enjoy the awesome view of Monterey Bay from campus
• Contact improv on the beach
• Have an organic beer at the local brewery - I like the Devout Stout
• Bike to Monterey or Palo Alto
• Mountain biking in the trails and along the ocean
• Hike in the beautiful mountains, cross a stream while doing so
• Walk along the beach and enjoy the sunset
• Take a dip in the ocean
• Have a barbeque in one of the parks
