I am a professor of political science at Stanford University, with courtesy appointments in Philosophy, Law, and Education. I teach and write about the governance of frontier science and technology. In the past, I've written about philanthropy in democratic societies, and the purposes of public education.

I serve as associate director of the Institute for Human-Centered AI and as faculty director of the Ethics, Society, and Technology Initiatives at the Center for Ethics in Society.

I was an early advisor to Giving Tuesday and served as the founding board chair.
