I am a 4th year Ph.D. student of Computer Science and Engineering at Penn State, working with Dr Prasenjit Mitra and Dr Xiaofei Lu. My research interest lies in Computational and Cognitive Linguistics, and Data Mining.


I did my 2011 summer internship at NEC Labs, Princeton, NJ. My mentors were Dr Christopher Malon and Dr Bing Bai. We worked in multiple-choice question answering.


My 2010 summer internship was at IBM India Research Lab in New Delhi, under Sachindra Joshi. We worked in topic modeling of call center chats, in collaboration with Kumar A Dubey and Dr Shantanu Godbole.


I have worked in the CyDAR project. Some relevant details and pointers can be found here. While working in the ChemXSeer project, I redesigned the Gaussian file search engine.


Besides working in these projects as a research assistant, I am pursuing my own research on colloquialism (informality) detection and measurement at sentence-level. An informality measure of documents like F-score helps style-based classification, ranking and diversification of search results. Besides quantifying one of the most important register dimensions, F-score also correlates moderately with readability tests.


I did my undergraduate study in Computer Science and Engineering from Jadavpur University, Kolkata. My advisor was Prof. (Dr.) Sivaji Bandyopadhyay.
