I am a Software Engineer at Google. Before joining Google, I received my PhD under the direction of Prof. W. Bruce Croft at the Center for Intelligent Information Retrieval (CIIR), College of Information and Computer Sciences, University of Massachusetts Amherst. My research is focused on dense retrieval, conversational search, and other related topics in Information Retrieval and Natural Language Processing.
