Dr Christian Pfrang

Dr Pfrang’s research is in the area of gas-phase and heterogeneous atmospheric chemistry currently focusing on the fate of atmospheric aerosols and their impacts on air quality and climate change.  He is also studying reactions of initiators of atmospheric oxidation (in particular ozone and nitrate radicals) with volatile organic compounds (VOCs), e.g. stress-induced plant emissions.  Experimental studies mainly using levitation, monolayer, X-ray & neutron scattering techniques are complemented by computational work predicting the kinetic behaviour of species of atmospheric importance (e.g. co-developing the aerosol models K2-SUB, KM-SUB and KM-GAP).  Dr Pfrang is also aiming to link atmospheric chemistry to related research topics in meteorology, environmental & plant sciences to advance the understanding of the urban environment.
