I am currently pursuing my Ph. D. in the Department of EECS at MIT, working with Professor Alan Willsky as a member of Stochastic Systems Group in the Laboratory for Information and Decision Systems. I did my undergraduate work at Seoul National University (SNU) in South Korea majoring in EECS, and also spent a year at University of California, Santa Barbara as an extension student during my second year of undergraduate studies. My research interests include statistical signal processing, and in particular, multiscale Markov Random Fields for large-scale inference.

Resume December 2007

Learning Multiscale Graphical Models using Maximum Entropy Relaxation (September 2007 ~ )

Multiscale Gaussian Graphical Models and Algorithms for Large-Scale Inference (January 2006 ~ )

Conditional Random Fields with Local Regularities (Microsoft Internship Project, June 2007 ~ )

Video Key Frame Extraction and Sequence Matching (Undergraduate Project, January 2004 ~ July 2004)
