Dr. Zhao was with the US National Renewable Energy Laboratory before joining CUHK. He received Caltech PhD thesis prizes (2016, 2017), the Hong Kong RGC Early Career Award (2020), and the IEEE Power and Energy Society Prize Paper Award (2021). His research focuses on the control and optimization of networked systems, particularly power systems.
