Biographical details

Malcolm Possell is a Teaching and Research Fellow in the Department of Environmental Science with a specialisation in measuring and modelling fluxes of trace gases between the terrestrial biosphere and atmosphere. He is interested in research and teaching in biosphere-atmosphere interactions, including the effects of bushfires and climate change.

Malcolm graduated from the University of East Anglia (UK) with a B.Sc. (Hons) in Environmental Science and a Ph.D. in Environmental Science from Lancaster University (UK). Prior to working for the University of Sydney, he worked as a research associate at the University of Sheffield (UK) (2003-2004) and Lancaster University (2004-2010) on projects aimed at understanding the biosynthesis and emission of the volatile organic compound isoprene under different abiotic and biotic conditions.

Research interests

Dr Possell’s research interests are on the flux of trace gases, such as CO2, CO and volatile organic compounds, and particles between the biosphere and atmosphere and the mechanisms controlling these fluxes. Trace gases and particles have significant impacts on air quality and climate and subsequently on plant, animal and human wellbeing. His research in this area involves making laboratory and field studies of emissions directly from vegetation and determining how and why different biotic and abiotic stresses affect the biosynthesis and emission of these compounds. These stresses include herbivory, transient high temperatures, reduced and elevated CO2, and elevated ozone. More recently, his work focuses on trace gas emissions as a consequence of wildfires and understanding the factors controlling the composition of smoke. Results from these studies allow us to better parameterise the observed responses and improve trace gas emission models. As trace gas emission models are used within Earth System science models we can then attempt to assess how changes in fluxes impact all the interconnected components of the Earth system now and in the future.
