Physical

My research involves the development and application of state-of-the-art chemistry-climate models. With these models we are trying to answer a number of questions relevant to society: (i) What are the impacts of changes in man made emissions on the composition of the atmosphere (ii) how does the changing composition of the atmosphere affect climate (iii) how will a changing climate impact the composition of the atmosphere. One of the main areas of research in my group is trying to better understand the mechanisms of oxidation of biogenic hydrocarbons - in particular the oxidation of isoprene. Isoprene enters the atmosphere via emissions from plants and trees. Every year a mass roughly equal to that of the entire human population is emitted into the atmosphere! Owing to this, and its high reactivity, it is paramount to include isoprene chemistry in chemistry-climate models. However, the details of the chemistry vary wildly between models and isoprene chemistry has been suggested as a major cause of disagreement between model predictions of secondary pollutants.
