I work on DeepQA technology underlying Watson. On February 16, 2011, Watson took on grand champions Ken Jennings and Brad Rutter on the Jeopardy! game show, and won the grand challenge.

For details of the technology underlying Watson, see the IBM Journal of Research and Development, Special Issue on Watson.

My research is primarily in the area of Natural Language Processing. Specifically, I develop methods to accurately identify specific events and associated information in free text. In my doctoral research I have explored several pattern-based and machine learning approaches for event-oriented Information Extraction. My other research interests include automatic analysis of opinions and subjectivity in text, Word Sense Disambiguation, and computational representations for Lexical Semantics. I am also interested in applications of this work in the biomedial domain.
