Sarah H.Q. Li

Assistant Professor

Sarah Li will join the Daniel Guggenheim School of Aerospace Engineering in January 2025. Her research advances multi-agent models and algorithms to overcome challenges facing future air and space mobility systems. Her research lies at the intersection of game theory, stochastic control, and optimization to enable optimal and safe decision-making of autonomous systems in interactive settings. Sarah earned her Ph.D. in Aeronautics and Astronautics from the University of Washington and her B.A.Sc. in Engineering Physics from the University of British Columbia. She is currently a postdoctoral scholar at ETH Zurich in Information Technology and Electrical Engineering. She was a 2020 Zonta International Amelia Earhart Fellow and a 2022 University of Washington Condit Graduate Fellow. During her Ph.D., she interned with Microsoft Research to develop supply chain games and Loon to develop multi-disciplinary design optimization for stratospheric balloons.
