I am a Ph.D. candidate at the University of California San Diego Computer Science Department. My general area of interest involves conversational AI and recommender systems. Some of the recent projects involve hallucination in role-playing, conversational recommendation, factual knowledge in language models, and dialogue state tracking.
I received the Jacobs School of Engineering Fellowship at CSE, UC San Diego (2021-2022). Previously, I completed my B.Sc. and M.Sc. from Bangladesh University of Engineering Technology (BUET).
