Google veterans leaving to launch Discovery Loop, from left: Oriol Vinyals, Sanjay Ghemawat, Jeff Dean, and Quoc Le. Discovery Loop is based in Palo Alto, with what it describes as a lean team of its own. Joining Dean are Google senior fellow Sanjay Ghemawat, his collaborator of more than two decades; Google DeepMind research VP Oriol Vinyals; and Google Brain co-founder Quoc Le. Dean, who earned his UW computer science Ph.D. in 1996, gave no hint of his plans at the Allen School commencement. Listing problems he thought worth solving, he pointed the UW graduates toward “developing tools that accelerate scientific discovery and engineering.”
