I am a final year Ph.D. student of Computer Science and Engineering at University at Buffalo. I am fortunate to be supervised by Prof. Junsong Yuan. Prior to UB, I obtained my M.D. degree in oncology, where I was initially trained as an internal oncologist. My current research interest lies in visual reasoning and vision-language learning. In the medical domain, my ultimate goal is to empower medical AI systems with the ability of visual reasoning akin to human experts.
