Development and application of laser-based techniques for non-intrusive measurement of concentration, temperature, droplet- and particle-size, as well as flow velocity in reactive flows
Quantitative imaging measurements of concentration and temperature distribution in flames, internal combustion engine cylinders, reactive and non-reactive flows
Development of minimal invasive detectors for imaging measurements in cavities
Analysis of the spectroscopic properties of organic molecules and nanoparticular substances
Analysis of processes in internal combustion engines and turbulent reaction processes based on laser-spectroscopic method

Analysis of the kinetics of combustion, ignition and particle formation reactions in shockwave reactors on the basis of elementary reactions and with full reaction schemes. Reactions are started by the instantaneous temperature rise in a shock wave and subsequent reactions are monitored with optical techniques and mass spectrometry
Measurement of ignition delay times as a function of pressure and temperature for pure compounds and commercial fuels
Determination of extensive reaction schemes for various fields as combustion chemistry, pyrolysis of large molecules, particle formation, and particle oxidation
