I am a Lecturer in the Department of Electrical and Electronic Engineering at Imperial College London, where I was an EPSRC Innovation Fellow from 2018 to 2020. Before being an academic, I was with General Electric (GE) Global Research Centre in Shanghai, where I led and participated in a series of R&D projects on the integration of renewable power into grids.

My research career started with power-electronic converters and control for solar power systems. The IPs generated from my early work have been translated into a spinout (Hoymiles) listed in Shanghai Stock Exchange. After joining Imperial, my research interests have been extended to power-electronics-based power systems, including power-electronic technologies to support power system stability, and system stability analytics considering the behaviour of power electronics. I recently opened another thread of research on the numerical and computational methods for power system analysis and simulation. A detailed description of my research work can be found here. A list of my publications and citations is available at Google Scholar. I hold seven patents including six Chinese patents and one US/EU patent.

Besides my main research work, I have hobbies in software and hardware development (and hacking), especially in real-time computing and digital twins. I'm one of the three international maintainers for the open-source real-time operating system (RTOS) RT-Thread. I'm a co-founder of the open-source power system analysis/simulation toolbox Simplus Grid-Tool. I created and am commercialising a real-time digital twin system named Simplus Real-Time. 

To PhD Students

I am recruiting talented PhD students who have interests in power electronics, power systems, and real-time computing. A candidate is expected to have a master's degree in Electrical and Electronic Engineering, Control (Automation), Computer Science, Maths, Physics, and other related disciplines. I have a fully-funded PhD studentship available to international and home-fee students. I also support the application of departmental and college studentships. The research topics for potential PhD students include but are not limited to:

  • Numerical computation for dynamical analysis and simulation of stiff and large-scale power systems.
  • Power-electronic technologies to support power system stability.
  • Model-data-driven methods for stability analysis of power-electronic-based power systems.
