Jeff Dean, Google's former chief scientist, posted his weekly workout: two soccer games, two gym sessions, yoga, and 8K runs. He left Google this month to cofound AI startup Discovery Loop.
Alpha Score of 75 reflects strong overall profile with moderate momentum, moderate value, strong quality, strong sentiment.
Jeff Dean, Google's former chief scientist and employee No. 30, shared the workout routine that feeds the legend. The man who inspired Chuck Norris-style jokes inside Google – "When Jeff Dean compiles, the compiler looks for errors in its own code" – is putting in real mileage.
Dean posted a calendar from his final day at Google during the KDD Conference in Jeju, South Korea, on his X account Tuesday. One user spotted yoga in his schedule and asked about his weekly workout.
His mix, he said: two soccer games in a 25-and-over league, two gym sessions, two yoga classes, three to four 8-kilometer runs to work, three to four 8-kilometer bike commutes, and one longer run or ride on the weekend.
Asked how he protects his joints, Dean pointed to his shoes. "Squishy running shoes and replacing the shoes pretty often and arch support inserts," he said. "It's my ankles that are more troublesome (too many basketball sprains years ago)."
The routine comes as Dean leaves Google after 27 years to cofound Discovery Loop, an AI startup that automates parts of scientific and engineering research. He departed alongside longtime Google researchers Sanjay Ghemawat, Oriol Vinyals, and Quoc Le. Alphabet is a founding investor in Discovery Loop, and Google Cloud is a partner.
A representative for Dean declined to comment.
Dean's move is part of a broader reshuffling at Google. Demis Hassabis moved from CEO of Google DeepMind to chair and chief scientist of Alphabet, while DeepMind CTO Koray Kavukcuoglu took over day-to-day operations.
