Robert de Groot is a physical scientist with the U.S. Geological Survey Earthquake Science Center. He is a member of the ShakeAlert Earthquake Early Warning System operations team based in Pasadena, California. He is responsible for managing communication, education, outreach, and technical engagement throughout the ShakeAlert System service area with over 50 million people in California, Oregon, and Washington. His work includes recruiting technical partners who use ShakeAlert data to deliver alerts to people, such as on their cell phone, and to trigger automated actions like slowing down trains and closing valves to protect water supplies. Since ShakeAlert is a people-focused earthquake early warning system, de Groot works closely with over thirty social scientists from around the world to improve how people interact with the ShakeAlert system with the goal to improve human safety. He holds a PhD in science education from the University of Southern California. In 2015 he was named a fellow of the American Chemical Society.
