Ricardo Martin-Brualla

Hi! I live in Seattle and enjoy anything 3D with algorithms and machine learning! Currently I work at Google, where I lead an effort on generating 3D assets for all products in Google Search, using NeRFs and Generative AI. Our tech is already launched for shoes in the US!

We are hiring research scientists and software engineers, please reach out if you are interested in a role!

Previously at Google, I worked for five years on Project Starline, a futuristic 3D telepresence system. Before that, two of my projects went viral online: timelapse mining from Internet photos in 2015, and a timelapse of Seattle from the Space Needle in 2018.

I did my PhD in Computer Science and Engineering at the University of Washington in 2016 with Steve Seitz as my advisor. and my bachelors at Barcelona Tech / UPC. I taught Computer Vision at the University of Washington in 2018. I grew up in Madrid and attended the Deutsche Schule Madrid, where I learned a lot of German.

I love traveling and seeing other parts of the world, ideally by human power. Most recently, my wife and I crossed Alaska from Ketchikan to Kotzibue on foot, packraft and cycling. We wrote a blog about it at north2arctic, and also have an instagram about it. After my PhD in 2016, I backpacked across Iceland, and explored Madagascar and Central Asia. After my undergrad in 2010, I traveled by bicycle around New Zealand, visiting the antipodes of my house in Madrid. I also went to Vanuatu and climbed a remote volcano to see lava bubbling.
