I graduated in Summer 2005 and was a Computer Scientist at the AI Center of SRI International till Spring 2007. I am now a Senior Research Scientist at Google Research. My main areas of research interest are machine learning, data mining, social network analysis, information retrieval, statistical pattern recognition and optimization. I did my PhD from the department of Computer Sciences at the University of Texas at Austin. My PhD work focused on the development of new semi-supervised clustering algorithms, with applications to text analysis and bioinformatics. My PhD advisor was Prof. Raymond Mooney, who leads the Machine Learning group at UTCS. I did my MS from the Computer Engineering Department at the University of California at Santa Cruz in 2000. At UCSC, I worked with the Computational Biology and Machine Learning group. I did my MS Thesis in bioinformatics, on development of a constrained mini-threading algorithm for protein structure prediction, under Prof. Kevin Karplus. I completed my B.Tech (Hons.) from the Department of Computer Science and Engineering at the Indian Institute of Technology, Kharagpur in 1998, where I did a thesis on fast lossless image compression using cellular automata under the guidance of Prof. Parimal Pal Chaudhuri and Prof. Dipanwita Roy Chowdhuri.
