Chirag Parikh

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

Interests: My research lies at the intersection of computer vision and machine learning, with a focus on addressing the challenges of developing ADAS solutions for dense, unstructured traffic environments. I am currently working on video-based driver behavior understanding and interactive video question answering to enhance explainability in driving scenarios.

Bio: I completed my B.E. from Birla Institute of Technology, Mesra in 2017, where I worked on robotic vision projects with the college robotics society. Before starting my PhD in 2022, I developed computer vision systems for driver behavior monitoring and satellite-based cropland analysis in industry.
