Biography

Research has been published at CVPR, ICCV, ECCV, and ICLR.

I am currently a researcher at AMI Labs, where I aim to enable human-like visual understanding and learning in machines. Prior to AMI, I did research into self-supervised learning, video representations, and multimodal modeling at FAIR with the JEPA team. I was a core contributor to V-JEPA 2 and MetaMorph, and a lead for WebSSL and Beyond Language Modeling.

As of March 2026, my open-sourced models from FAIR have over 1M total downloads and 500 citations. Prior to FAIR, I was at Amazon Prime Video, where I worked primarily on video/multimodal representation learning with a long-term vision of cracking the "long"-video understanding problem.

My notable production work includes: 1) Prime Video automated advertisement insertion at scene boundaries, 2) semantic-knowledge graph for efficient zero-shot metadata classification at catalog scale, 3) visual-search for carousel recommendations, and 4) content moderation and compliance models.

I graduated magna cum laude from Princeton University with a B.S.E in computer science in 2019. My life's ambition is to empower people to do their best work and strive to be better versions of themselves.

Key Papers
This work proposes a motion-guided masking algorithm (MGM) which leverages motion vectors to guide the position of each mask over time and shows that MGM generalizes better to downstream transfer learning and domain adaptation tasks on the UCF101, HMDB51, and Diving48 datasets.
