I am interested in methane and climate feedbacks.  I started my PhD in October 2019 and have been evaluating the treatment of methane in climate models. The main metrics used for comparison include methane lifetime, interhemispheric gradient and vertical profile. Most models prescribe a constant mixing ratio for methane at the surface and this means there are limitations to the feedbacks which can be included in the system. I am excited to start looking at data from the newly developed UKESM1 model with interactive methane emissions, including feedbacks such as due to wetland emissions. I will be looking at possible future methane trajectories and effectiveness of mitigation measures, and how the emissions from different sources (eg. anthropogenic, natural) will evolve over time.

4th Year Project

As part of my 4th year project I developed a 1D model to simulate isoprene emissions within a forest canopy. This was based on the measurements taken in the WISDOM field campaign in Wytham Woods in the growing season of 2018.
