Shelton, who has also worked at the Gates Foundation and a public education tech company, will lead the Chan Zuckerberg Initiative’s education efforts. Chan and Zuckerberg announced the foundation last year when their daughter, Max, was born. They also pledged to give away 99% of their Facebook shares, over their lifetime, to philanthropy. The foundation’s education efforts will focus on personalized learning and underserved communities, Zuckerberg said in a post on Facebook.

Priscilla’s work as a pediatrician and a teacher has taught her how important life outside the classroom is to a child’s ability to learn inside it. And now Jim will bring all of his own experience in improving personalized learning and helping underserved communities,” he wrote. The Chan Zuckerberg Initiative was initially controversial because of its limited liability corporation status instead of a non-profit. Zuckerberg has defended the decision by saying it affords the organization more flexibility when it comes to allocating funds. Shelton is only the latest Washington official to go work for Silicon Valley.
