Together with amazing co-organizers, Blase Ur, Yan Shvartzshnaider, and Helen Nissembaum, we held the Third Annual Symposium of Applications of Contextual Integrity at the Department of Computer Science on September 30 and October 1, 2021. This was hybrid event co-organized with CornellTech and went off successfully thanks to volunteers from the AIR lab and SUPERgroup and others from the Department of Computer Science! For instance, Kelly co-chaired a session at the event. Thanks also to our support team, Sandy Quarles, Nita Yack, Tom Dobes, Rob Mitchum, and Rene Noyola!
