Background

In 2015, I completed my D.Phil Programme in Control Engineering in Department of Engineering Science, University of Oxford, under the supervision of Prof. Antonis Papachristodoulou. Before joining Oxford, I received my B.Eng degree from Department of Automation, Tsinghua University, China, in 2011. From Sep. 2014 to Dec. 2014, I was a visiting graduate student in Prof. Na Li's group in School of Engineering and Applied Sciences (SEAS), Harvard University.

Research Interests

• Networked systems: Optimization and control for smart power networks; HVAC system control in energy efficient buildings; network congestion control/utility maximization; consensus of multi-agent systems through mean-field games; linear (time-delay) systems with input saturation and delay.

• Convex optimization, reverse- and forward-engineering.

• Nonlinear dynamical systems, Lyapunov stability.
