The research interests of the group focus on free radical reaction kinetics and oxidation chemistry in gas-phase under low-temperature combustion and atmospheric conditions. Kinetics of free radical reactions are studied in time-resolved manner using a laminar flow reactor which is coupled to a photoionization quadrupole mass spectrometer. Radicals are produced and reactions initiated photolytically and reactions are investigated as a function of temperature and pressure. New experimental apparatus is under construction to study and produce labile oxygenated compounds which are important intermediates under low-temperature combustion and atmospheric conditions. The kinetic and oxidation chemistry data obtained using these instruments are important for modelling and understanding combustion processes and atmospheric reaction chemistry.
