His work on topics ranging from tax policy and unemployment insurance to education and affordable housing has been widely cited in academia, media outlets, and Congressional testimony. Chetty received his Ph.D. from Harvard University in 2003 and is one of the youngest tenured professors in Harvard’s history. Before joining the faculty at Harvard, he was a professor at UC-Berkeley and Stanford University.
