Part 1: As a teenager, Bri Riggio struggles to understand her eating disorder and connect with her psychologist father. Part 2: Seth Baum, an expert in global catastrophic risk, makes waves when he suggests a solution to the threat of nuclear winter. Bri Riggio has spent the last six years working at various institutions of higher education, from a study abroad program in Greece to George Mason University, where she now supports the Office of Research at the executive level. While not a scientist by training, she has always loved research and the process of learning. She stupidly spent an extra year in graduate school after choosing to base her Master's thesis on a social science methodology that she didn't know and just barely managed to finish her MA in Conflict Resolution this past spring. To keep her sanity, she runs marathons, plays video games, and looks for opportunities to tell her stories. Dr. Seth Baum is Executive Director of the Global Catastrophic Risk Institute, a nonprofit think tank that Baum co-founded in 2011. His research focuses on risk and policy analysis of catastrophes that could destroy human civilization, such as global warming, nuclear war, and infectious disease outbreaks. Baum received a Ph.D. in Geography from Pennsylvania State University and completed a post-doctoral fellowship with the Columbia University Center for Research on Environmental Decisions. His writing has appeared in the Bulletin of the Atomic Scientists, the Guardian, Scientific American, and a wide range of peer-reviewed scholarly journals.
