Overview
I have received a B.Eng. degree in Electrical Engineering and its Automation from Northeast Electric Power University, Jilin, China, in 2011, the M.Sc. degree in Power Engineering from Nanyang Technological University, Singapore, in 2013 and the Ph.D. degree in Electrical Engineering from Cardiff University, Cardiff, U.K, in 2018.
From 2013 to 2016, I was a Marie Curie Early Stage Research Fellow funded by the European Union’s MEDOW project. I have been a Visiting Researcher at China Electric Power Research Institute and Global Energy Interconnection Research Institute, Beijing, China, at Elia, Brussels, Belgium and at Toshiba International (Europe), London, U.K. I have been a Research Associate at the School of Engineering, Cardiff University since 2017. My research interests include protection and control of HVDC and MVDC technologies, power electronics, renewable energy integration, stability and control of hybrid AC/DC grids, reliability modeling and evaluation of power electronics systems for different applications.
I am a Chartered Engineer in the U.K, and am an Associate Editor of the CSEE Journal of Power and Energy Systems. My Ph.D. thesis received the First CIGRE Thesis Award in 2018.
