I’m an international relations specialist best known for my work on human rights, international norms, transnational advocacy networks and social movements, and transitional justice. I teach at the Harvard Kennedy School, where I’m the Ryan Family Professor of Human Rights Policy and the Carol K. Pforzheimer Professor at the Radcliffe Institute for Advanced Study. I’m trying to write both for scholars and for members of the public interested in human rights and justice, especially in the books The Justice Cascade, Evidence for Hope, and Activists beyond Borders. My books have been awarded prizes, including the Grawemeyer Award (for Ideas for Improving World Order), the Robert F. Kennedy Center Book Award, and the WOLA/Duke University Award. My most recent book Evidence for Hope: Making Human Rights Work in the 21st Century (Princeton University Press, 2017) documents the legitimacy and effectiveness of human rights law, institutions, and movements. I’ve been a Fulbright Scholar in Argentina and a Guggenheim fellow.
