Kevin Starr directs the Mulago Foundation and its Rainer Arnhold Fellows Program, focused on scalable solutions to meet the basic needs of the very poor. He came to his current position in 1994 — after friend and mentor Rainer Arnhold died while the pair were working together in Bolivia — at the request of Arnhold’s family. In 2003, Starr established the fellows program to apply Mulago’s principles and tools to help social entrepreneurs turn ideas into lasting change. He teaches and mentors fellows and serves as chairman of Big Bang Philanthropy, a group of funders working to direct money to those best at fighting poverty. Previously, Starr had a career in medicine.
