Plenary Lecture Alan Alda is an actor, writer, director, and visiting professor at the Alan Alda Center for Communicating Science at Stony Brook University, where he helps current and future scientists learn to communicate more clearly and vividly with the public. In collaboration with theater arts faculty at Stony Brook, he is pioneering the use of improvisational theater exercises to help scientists connect more directly with people outside their field. Alda is best known for his award-winning work in movies, theater, and television, but he also has a distinguished record in the public communication of science. For 13 years he hosted the PBS series Scientific American Frontiers, which he has called “the best thing I ever did in front of a camera.” After interviewing hundreds of scientists around the world, he became convinced that many researchers have wonderful stories but need to learn how to tell them better. That realization inspired the creation of Stony Brook’s multidisciplinary Alan Alda Center for Communicating Science in 2009.
