I am a Research Engineer with the Power Systems Engineering Center at National Renewable Energy Laboratory (NREL). My research focuses on control and optimization of power systems. I am particularly interested in power system dynamics and stability, frequency and voltage regulation, and control of distributed energy resources.
I got my PhD in Electrical Engineering at California Institute of Technology, and B. Eng. in Automation at Tsinghua University.
