We are excited to welcome Patrick Kelly, a Buffett Post Doc who received his doctorate in history from the University of Chicago and previously was a Mellon fellow at the University of Wisconsin-Madison. He researches and teaches broadly across modern global history, and is particularly interested in how and why people, ideas, and diseases cross national borders. This interest shaped his first book, Sovereign Emergencies: Latin America and the Making of Global Human Rights Politics (Cambridge, 2018), which examines the intersection of Latin American and global human rights politics since the 1970s. It also informs his second book project on the global history of AIDS as a metaphor for contemporary globalization.
