Moderator: Ben Adida, VotingWorks
Panelists: Mike Judd, CDC COVID-19 Exposure Notification Initiative; Ali Lange, Google; Tiffany C. Li, Boston University School of Law; Marcel Salathé, EPFL


With the unprecedented COVID-19 pandemic came an unprecedented technology and public health collaboration: Google and Apple joined forces with public health departments to deploy a mechanism for notifying people of their possible exposure to the virus. How was this decision made? What were the tradeoffs? How is it going? If we had to do it all over again, what might we do differently? And most importantly, what does the future of app-based contact tracing look like? Join us for a lively discussion bringing together policy, epidemiology, legal, and public health experts on one of the most important cross-disciplinary collaborations of our time.
