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 is focused 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 numerical models. This combination of observations and modelling provides an ideal mechanism by which to test and further our understanding of the processes controlling the lifetimes and concentrations of trace species, and their implications for air quality and climate change.

A current focus of my research is on the potential application of low cost sensor technologies to atmospheric research questions. These small, low power devices could provide data on atmospheric chemical composition and variability over much larger spatial and temporal scales than is accessible by current instrumentation. In order to maximise the potential of these devices, my group is currently developing new sampling strategies and data analysis methods, such as the application of machine learning algorithms to extract information from complex signals. This work is funded through my Marie Sklodowska Curie fellowship and the UK National Centre for Atmospheric Science, and will ultimately provide new tools with which to probe the atmosphere.
