NEW! My Ph.D. Dissertation. (9/2002)

Biographical Sketch

I received my Bachelor's degree in Computer Engineering from the University of Michigan in 1997 and since then, I have been a graduate student in the Computer Science Division of the EECS department at the University of California, Berkeley.

Research

I have been a graduate student researcher in the at the International Computer Science Institute since 1997. I am a member of the Speech Group (formerly the Realization Group).

My research interest lies in automatic processing of spoken language, melding insights from statistical analysis of realistic speech corpora and advanced techniques of machine learning. I am also interested in applying the concept and techniques developed from speech research to a broader context of perception, human-computer interaction, and language learning.

My official advisor is Prof. Nelson Morgan, and Dr. Steven Greenberg and Dr. Lokendra Shastri are also advising me on my research.
