I received B.S. in Electrical Engineering (EE) from Yonsei University (in Korea) in 2000, M.S. in EE from Seoul National University (also in Korea) in 2002, and am pursuing Ph.D. in EE at USC (in Los Angeles, CA, USA) from 2002. My advisor is Dr. Shri Narayanan, and I've been working with him at Speech Analysis and Interpretation Laboratory (SAIL) since 2003. My research interests include signal processing and pattern recognition for data classification or mining, specifically in terms of speaker identity, e.g., speaker clustering.
