Justin Walker serves as the Executive Director of the Global Game Changers, while also working as an assistant law professor at the University of Louisville. A graduate of Harvard Law School and Duke University, he clerked on the Supreme Court for Justice Anthony Kennedy, and on the DC Circuit for Judge Brett Kavanaugh.
