I talk with Dr. Daniel Halperin, author of the book "Tinderbox: How the West Sparked the AIDS Epidemic and How the World Can Finally Overcome It", co-authored with journalist Craig Timberg. Daniel is an epidemiologist and medical anthropologist with extensive experience studying HIV and AIDS as an academic, combatting its spread as the Senior HIV Prevention and Behavior Change Advisor at USAID, and consulting over the years with international partners to influence policy. He also had a front row seat to a fascinating piece of history in the fight against HIV and AIDS.
