About

I am a Ph.D. student in Data Science at Stony Brook University, supervised by Sima Mofakham and Petar M. Djurić. My broad research interests include multimodal large language models (MLLMs), video understanding, agentic AI, motion analysis, and clinical applications of AI.

My current work focuses on MLLM post-training, MLLM-based agents, LLM safety, and AI for ICU settings.

Previously, I earned my M.S. in Data Science at the Halıcıoğlu Data Science Institute, UC San Diego, where I worked with Tauhidur Rahman on event-based vision, synthetic event generation, and continuous motion estimation.

For research inquiries, please contact me by email.
