Welcome !!

Hi everyone,

I am currently an IBM PhD Fellow in the department of Computer Science and Engineering, IIT Kharagpur and a member of Complex Network Research Group (CNeRG). Prior to this, I was a Microsoft Research India PhD Fellow from 2014-2016. I am working under the supervision of Prof. Animesh Mukherjee. My research interests broadly include Computational Social Science : with key focus on popularity of entities in social QA (Quora, Stack Overflow etc.), hashtag popularity and evolution of linguistic entities like lexical compounding, lexical blending on social media.

I am currently working on understanding popularity aspects of various linguistic entities (hashtags in Twitter, topics/tags in Social QA sites like Quora, Stack Overflow). Our new work on hashtag compounding has been published in CSCW 2016 and has received "Best Paper Honorable mention" award. I am also working on understanding anomalies (spam, rumor) in social network with active help from Prof. Arjun Mukherjee at University of Houston in the area of deep NLP. I worked in developing computational models to understand how word-meaning association is formed in a multi-agent scenarios and what are the factors influencing the phenomena with help from Dr. Francesca Tria, ISI Foundation, Turin, Italy and Dr. Vittorio Loreto, ISI Foundation, Turin, Italy and Department of Physics, Sapienza University, Rome . Apart from these, I have also worked on emergence and evolution of language variation with help from Dr. Tyll Kruger, Wroclaw University of Technology, Poland.

I will be graduating this Fall and looking for Postdoc opportunities.

Apart from engaging myself in research activities, I am a sports enthusiast and like travelling. I am a die-hard fan of Rafael Nadal and Sourav Ganguly.
