His laboratory specialises in combustion and advanced flow diagnostics. The combustion lab has several lab scale burners for both fundamental research and teaching. An industrial gas turbine combustor (1 MW) is available for testing and research. A high pressure test burner up to 20 bar has been built for combustion studies. The burner has two quartz windows and two pure silicon windows, which are transparent to infrared and longer wavelength (e.g. Terahertz wave).
