We are studying wide spectrum of energy-related phenomena ranging from atomic/molecular scale to large scale energy systems and global environmental issues based on thermal and fluid, combustion, reaction and energy engineering background. Current research interests include clean and high efficiency hydrogen energy systems, fuel cells, clean and high efficiency coal/biomass technology for global protection, atmospheric pressure non-equilibrium plasmas and application to advanced materials conversion. We are exploring the frontier of the interdisciplinary field associated with energy phenomena.
