Gabriel Barth-Maron

Portrait of Gabriel Barth-Maron

Research Director · Google DeepMind · London

I build frontier multimodal generative models and the research systems behind them.

I currently co-lead Gemini Omni, a model family that brings Gemini's reasoning together with generative media. Previously, I co-led Veo across its first three generations.

Current work

Earlier work

I helped build Gemini's multimodal foundations, led technical development for Gato, and pioneered distributed reinforcement learning at DeepMind. That work also produced the open-source systems Acme, Reverb, and Launchpad.

I hold a BA in Mathematical Economics and an ScM in Computer Science from Brown University.
