I am a PhD candidate at the University of Massachusetts Amherst affliated with Center for Intelligent Information Retrieval under the supervision of W. Bruce Croft. My current research focuses on looking at answer passage relationships for improving tasks such as Question Answering and Conversational Search. Broadly, I am interested in Information Retrieval, Natural Language Processing and Machine Learning.
Prior to joining UMass to pursue a PhD, I completed a Masters in Computer Science specializing in Natural Language Processing from Columbia University, New York. I also worked as a Research Intern with Microsoft Bing in the summer of 2016. Before starting graduate studies, I worked as an IT consultant in India.
