I explore research initiatives in the area of Natural Language Processing and, within this realm, have worked on event-based information extraction, opinion/sentiment analysis, computational representation of lexical semantics, and their applications in the biomedical domain. At IBM, I work in the Knowledge Structures Group, which focuses on improving advanced search technology through the use of natural language processing and machine learning techniques.

I am currently working on DeepQA technology underlying the Watson System, which competed in the IBM Jeopardy! grand challenge. Among the DeepQA system components I have worked on are those dealing with temporal reasoning, question decomposition, lexical constraint recognition and answer type recognition.

I have a PhD in Computer Science from the University of Utah, a Master's degree in Computer Science from the University of Minnesota, and a Bachelor's degree in Computer Engineering from the University of Pune (India).

When I am not thinking about research, I like to travel, ski and play basketball (in no particular order).
