Sarah Tishkoff: "Human Origins in Africa" // Engaging Minds is a series of on-the-road lectures by Penn faculty -- and engaging minds is exactly what they do. At an Engaging Minds event Penn alumni and faculty meet face to face around Penn's cutting-edge research and discoveries, and connect it to the challenges of our day. It's lively. It's intelligent. It's engaging. (Engaging Minds 2009-2010 Season) www.alumni.upenn.edu/engagingminds
