Profile

I obtained my BSc and MSc degrees from Tsinghua University in Beijing, China. My PhD research was undertaken at the University of Sheffield, and was on the dynamics of vented explosions in the context of the safety of offshore platforms.

Upon completion of my PhD, I joined Edinburgh University as a post-doctoral research fellow. I worked at the Health and Safety Laboratory at Buxton on an intensive experimental investigation of tunnel fires, and also on the CFD study of the mechanisms of the King´s Cross Underground Station fire.

After Edinburgh University, I returned to the University of Sheffield as a lecturer in Chemical Engineering.

Research interests

My current research interests include hydrogen energy systems, fast fire spread phenomena in buildings and underground structures, tunnel fires, dynamics of fires and explosions, combustion and heat transfer in industrial furnaces, hazard analysis and risk assessment of process industry and flow visualization.
