As a Senior Research Scientist and Manager at Adobe Research, my work sits at the crossroads of generative models, visual understanding, and creative expression. I’ve spearheaded core technologies like inpainting and outpainting, now powering Generative Fill and Expand in Photoshop, Lightroom, and Firefly — tools used by millions, and recognized by TIME as one of the Best Inventions of 2023. Today, my focus is on designing unified multimodal models that can both generate and comprehend — bridging the gap between input and intent.
I received my Ph.D. in Computer Science from the University of California, Davis, advised by Prof. Yong Jae Lee. Earlier, I completed my M.S. in Robotics at Carnegie Mellon University, where I worked with Prof. Alexei Efros and Prof. Kayvon Fatahalian. I earned my undergraduate degree in Computer Science and Engineering from IIIT Hyderabad under the guidance of Prof. P. J. Narayanan. I was a Robotics Institute Summer Scholar (RISS) at CMU and have interned at Intel Labs, Allen Institute for AI (AI2), and Facebook AI.
