Chirag Parikh

I am a PhD student at the Center for Visual Information Technology (CVIT - Mobility), IIIT Hyderabad, supervised by Prof. Ravi Kiran Sarvadevabhatla.

Research Interests: My research focuses on grounded video understanding with multimodal models. I am particularly interested in visual grounding, multimodal reasoning, and improving reliability of Multimodal LLMs for dynamic real-world scenes. My work spans both intelligent transportation and more general video domains, with the goal of developing models that can reason about events and interactions, localize relevant entities in space and time, and ground their outputs in visual evidence.

Bio: Before my PhD, I worked on intelligent visual systems for driver behavior monitoring and satellite-based cropland analysis in industry and on robotic vision projects during my undergrad.

I am actively seeking research internship opportunities for 2027, please feel free to reach out by email.
