My research focuses on economic and enviromental analysis of science and engineering projects that can potentially contribute to the net-zero emissions goals and the global energy transition. The technologies include, but not limited to, low-carbon fuels, low-emission combustion and carbon capture. Techno-economic analysis and life-cycle assessment are the major methodologies to be applied in the research. I also broadly follow business trend and market movement of clean energy, circular economy, hydrogen economy and carbon capture, storage and utilization.
