In Their Own Words chronicles the stories of scientists who have made great contributions to their fields. These short histories provide our readers a way to learn from and share their experiences. We publish the results of these conversations in the pages of BioScience and on our podcast, BioScience Talks. This history is with Dr. Osvaldo Sala, who is the Julie A. Wrigley and Regents’ and Foundation Professor and the founding director of the Global Drylands Center, at Arizona State University.
