Research Interests

Climate change and air quality are two of the major challenges facing modern society, and these are both directly impacted by the chemistry of the troposphere. My research focuses on improving our understanding of the processes that control the chemical composition of the troposphere, especially those driven by highly reactive species known as radicals. This is achieved through novel instrument development, field observations and the use of computational models. Combining field observations of key atmospheric components with computational modelling allows us to test and further our understanding of the processes controlling the lifetimes and concentrations of key atmospheric species. By understanding the chemical processing of atmospheric species we can better understand the implications for air quality and climate change.

A current focus of my research is on the role of chlorine as a tropospheric oxidant. As part of my recently funded ERC  award “Quantifying the impact of tropospheric chlorine oxidation chemistry” (Trop-ClOC), I intend to use a combination of instrument development, fieldwork and modelling to challenge the state-of-the-science representation of chlorine chemistry in atmospheric chemistry models.
