Professor Christian Pfrang DPhil (Oxon) BSc (FU Berlin)

Professor Christian Pfrang

Professor of Atmospheric Science

Prof. Pfrang’s work is mainly focussed on gas-phase and heterogeneous atmospheric chemistry exploring 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. Prof. 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 with a recent focus on indoor air quality.

Experimental studies mainly developing levitation, monolayer, thin-film, 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, KM–GAP and most recently the modelling framework MultilayerPy). Key applied topics include cooking emissions and their fate & health impact, the impact of air pollution on pollination, the ability of indoor plants to improve air quality, the air quality performance of urban greenery and the impacts on vulnerable groups associated with these topics.

Qualifications

DPhil in Physical & Atmospheric Chemistry (University of Oxford); BSc in Chemistry (FU Berlin); Vordiplom in Chemistry (TU Munich); Post-Graduate Certificate in Academic Practice (University of Reading)

Biography

Christian Pfrang studied chemistry at the TU Munich, University of Oxford, and FU Berlin before his DPhil in Physical Chemistry with Prof. Richard P. Wayne at the University of Oxford. Following a stint as Carlo Schmid Fellow in the research department of the European Centre for Medium-Range Weather Forecasts (ECMWF) and a Leverhulme Visiting Fellowship at Royal Holloway University of London, Prof. Pfrang took up a tenure-track RCUK Academic Fellowship at the University of Reading in 2007 before becoming Lecturer and Associate Professor of Physical & Atmospheric Chemistry. In 2016, Prof. Pfrang was a Visiting Professor at the University of Lille (France). In 2018, Prof. Pfrang moved to a Senior Lecturer post in the School of Geography, Earth and Environmental Sciences at the University of Birmingham, where he was promoted to Reader and then Professor of Atmospheric Science while retaining his link to Reading as a Senior Visiting Research Fellow in the Department of Meteorology. Prof. Pfrang’s core expertise is atmospheric chemistry of aerosols, developing novel experimental and modelling tools often involving large-scale facilities, but he also has research interests in indoor air quality, urban greening, and wider implications of air pollution and climate change.

Teaching

LM Air Pollution Control Technology, LM Carbon Management, Air Pollution Chemistry

Postgraduate supervision

Atmospheric Chemistry and Physics, Aerosol Studies, Gas-phase Kinetics and Reaction Products, Indoor Air Quality, Plant-Pollution Interactions and Urban Greening.

Research

Prof. Pfrang’s research is mainly in the area of gas-phase and heterogeneous atmospheric chemistry focussing 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.

Prof. 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 with a recent focus on indoor air quality.
