My research focus is in the analysis of informal user-generated content on social media platforms. I am particularly interested in problems related to understanding what people write (named entity identification), how they write (characterizing word usages) and why they write (user intents, sentiment, opinion expression mining). I am also interested in studying the effects of these micro-level variables of user-generated content (along with the properties of the people and the network generating it) on emerging social phenomena on the Web. My doctoral thesis research is supported by the following grants, primarily based on my work:

IBM UIMA Innovation Award 2007

Microsoft's Beyond Search - Semantic Computing and Internet Economics Award, 2008


I defended my doctoral thesis in August 2010 and will be joining IBM Research Almaden as a Research Staff Member.

I am an alumnus of the Knoesis Center in the Computer Science dept. at the Kno.e.sis Research Center in Wright State University and was previously with the LSDIS Lab at the University of Georgia. I moved to Ohio when my advisor Amit Sheth took up the LexisNexis Ohio Eminent Scholar position in Jan 2007. Further back in the day, I got my bachelors in Management Studies with a specialization in Computer Science from the Birla Institute of Technology and Science, (BITS-Pilani) in India.
