I am a third-year Computer Science PhD candidate at the University of Massachusetts Amherst (UMass) working with Prof. W. Bruce Croft. I am currently a research assistant at the Center for Intelligent Information Retrieval (CIIR). My research interests include various aspects of information retrieval (IR), recommender systems, and text mining. I am currently focusing on modeling the core IR problems, e.g., query representation, document representation, and ranking, via (deep) neural networks. I regularly publish and serve as PC member in major IR venues.
During my PhD, I completed two research internships at Google (summer 2016) and Microsoft (summer 2017). Prior to UMass, I was fortunate to be advised by Prof. Azadeh Shakery as a Master student at the University of Tehran, Iran.
