Ricardo Martin-Brualla

I am a researcher interested in the intersection of AI and 3D, and excited about creating new products in that space.

Previously, I worked at Google for eight years, most recently as a Senior Staff Research Scientist, leading and managing a team working on generating 3D assets for all products in Google Search , using NeRFs, diffusion and video models. Before that, I worked for five years on 3D telepresence on Project Starline, from building the first end-to-end demos to leading the ML efforts for real-time novel view synthesis.

I obtained my PhD in Computer Science and Engineering at the University of Washington in 2016 with Steve Seitz as my advisor. Two of my PhD projects went viral online: timelapse mining from Internet photos, and a timelapse of Seattle from the Space Needle. I hold two bachelor degrees in Math and Informatics from Barcelona Tech / UPC.

Outside of work, I love the outdoors and adventures. During COVID-19, my wife and I crossed Alaska from Ketchikan to Kotzebue on foot, packraft and cycling. We wrote about it on our blog called north2arctic, and we were featured in the Mountaineers magazine.
