Divya Kothandaraman

I am a Computer Science PhD candidate at the University of Maryland College Park, working with Prof. Dinesh Manocha and Prof. Ming Lin at the GAMMA Lab. Previously, I was an undergraduate at the Indian Institute of Technology Madras, where I obtained a bachelors degree in Electrical Engineering, and masters degree in Data Sciences.

My broader research interests lie at the intersection of computer vision, deep learning and multi-modal learning. My recent works range from developing novel methods for generative AI tasks in controllable image and video generation such as personalization, novel-view synthesis, and prompt mixing to developing deep learning based solutions for computer vision tasks such as domain adaptation and video action recognition.
