Dr. Xu serves in the Electric Transmission & Operation Support Teams at Dominion Energy, with a focus on Synchrophasor data analytics and machine learning application. He received his Ph.D. in Electrical Engineering from the Univerisity of Tennessee, under the guidance of Dr. Kai Sun. Before that, he received his B.S. (2013) and M.Eng. (2016) in Electrical Engineering from Shandong University, under the guidance of Dr. Hengxu Zhang. Dr. Xu was a visiting student at Harvard University in 2020.

Dr. Xu is an active reviewer for many journals/conferences. He recieved the Outstanding Reviewer award in 2021, for his voluntary services for IEEE Transactions on Power Systems.

His main research interests include stability and control of power system dynamics, and data-driven approaches for system analysis and control. He also has interests in numerical simulation.
