Staff Research Scientist · Google DeepMind

Hi! I'm a Staff Research Scientist at Google DeepMind, working on Gemini Mid/Post-Training. Previously, I led evaluations for Veo and contributed to its pre-training, image-to-video capability, and post-training. My research interests are in building multimodal models for understanding and generation.

I graduated with a PhD in Computer Science from UC Berkeley in 2023, where I was advised by Prof. Trevor Darrell and was a member of BAIR. Prior to Berkeley, I completed my Master's at UIUC advised by Prof. A. Schwing and Prof. S. Lazebnik, and obtained my Bachelor's from NITK, India.

I am honored to be a Snap Research Scholar (2019) and a Siebel Scholar (2018).

Gemini 4 Argon

· Evals · Post-training

Designed and built an internal benchmark inspired by SWE-bench, and developed metrics and methods to measure and improve SFT models’ climbability during RL.

Gemini Omni

· Evals Lead · Multimodal Generation

Led evaluations across multimodal understanding and generation, including the creation and editing of video from text, images, audio, and video.

Veo 1, 2 & 3

· Pre-training · Post-training · Evaluation · Capabilities

Core contributor across three generations of Veo, with work spanning pre-training, image-to-video capabilities, and post-training. Led Veo’s evaluation efforts, combining human assessments and automated metrics to guide model development. Contributions included training-data optimization and supervised fine-tuning methods to improve generation quality.
