Tracy Tsai leads Cruise’s Sensors Systems Engineering team, which is responsible for defining, tracing, and verifying/validating requirements for all the sensors that perceive the outside world so that the autonomous vehicle can safely navigate. Previously, Tracy designed laser-based sensing systems for over 10 years, and she used those sensors for applications such as measuring greenhouse gasses and finding natural gas leaks. Tracy earned a BS in physics from Rice University and a PhD in Electrical Engineering from Princeton University.
