Brief Bio

I joined the Department of Computer Science and Engineering, Indian Institute of Technology, Kharagpur as an Assistant Professor on July 30th, 2013. Prior to that, I was working at INRIA Paris-Rocquencourt as a post doctoral fellow with Prof. Gérard Huet on The Sanskrit Heritage Site.

I did my B. Tech. in Electrical Engineering from Indian Institute of Technology, Kanpur. I received my Ph. D. from Intelligent Systems Research Centre, Faculty of Computing and Engineering, University of Ulster, UK. My PhD advisors were Prof. Laxmidhar Behera and Prof. T. M. McGinnity. The topic of my PhD dissertation was "Analytic Knowledge Discovery Techniques for Ad-Hoc information Retrieval and Text Summarization".

My main research interests include Text Mining, Natural Language Processing, Information Retrieval and Sanskrit Computational Linguistics.

Professional Activities

We organized sixth international conference on Sanskrit Computational Linguistics from October 23-25, 2019 at IIT Kharagpur. For more details, please visit this link.
