Bachelors in Technology (Hons.), Indian Institute of Technology, Kharagpur, Computer Science and Engineering (2014)
Ph.D., Purdue University, Computer Science (2022)

I am a fourth-year Ph.D. student in the Computer Science department at Purdue University. I work under the direction of Prof. Dan Goldwasser. I worked on Machine Comprehension for a while before switching to working on better representations for political events and entities via discourse contextualization. I started working on Natural Language Processing (NLP) in 2013 and have been involved in various projects since, with a year and a half away from NLP research in 2014-15.

I spent the summer of 2019 in Seattle as an Applied Scientist Intern in the Alexa Search team working under the guidance of smart and cheerful Kevin Small. We worked on a sports conversational multi-turn question answering dataset. We are working sporadically towards finishing our work from then and turn it into a useful publication for the community.

Prior to joining Prof. Goldwasser's lab, I worked as a Research Assistant in Prof. Pushpak Bhattacharyya's CFILT lab at the Indian Institute of Technology, Bombay back in India. I completed my undergraduate studies in the Indian Institute of Technology, Kharagpur in Computer Science and Technology. I was introduced to NLP by Prof. Niloy Ganguly and Prof. Pawan Goyal during my senior year at IIT Kharagpur.
