I am an Assistant Professor in the Manning College of Information and Computer Sciences (CICS) at the University of Massachusetts Amherst, where I also serve as the Associate Director of the Center for Intelligent Information Retrieval (CIIR). My research focuses on designing and evaluating statistical and machine learning models with applications to (interactive) information access systems, including search engines, recommender systems, and question answering. I am currently focusing on Neural Information Retrieval and Conversational Search. I received an NSF CAREER Award in 2022.

Prior to UMass, I was a Researcher at Microsoft, working on a wide range of problems related to search engines. I received my Ph.D. in 2019 from UMass under the direction of W. Bruce Croft. I am the recipient of the UMass CICS Outstanding Dissertation Award for my Ph.D. thesis on weakly supervised neural information retrieval. I obtained my M.Sc. and B.Sc. degrees from the University of Tehran.
