Biography

I am a Ph.D. student in Computer Science at the University of Central Florida, affiliated with the Institute of Artificial Intelligence (IAI). I work under Dr. Yu Tian and Dr. Mubarak Shah on problems in computer vision, with a focus on medical AI and models that connect medical images with clinical decisions.

I am interested in building systems that can understand medical images and videos, model how diseases change over time, and support safer decision-making in clinical scenarios.
