Biography

I am a PGR based in the Wolfson Atmospheric Chemistry Laboratories at the University of York working with Prof. Lucy Carpenter, investigating oceanic ozone deposition. I previously completed my Integrated Masters in Chemistry at the University of York, and spent my final year abroad at the University of Helsinki. Outside of my research I enjoy bouldering, hiking, and spending time with friends.

Project outline

My PhD project investigates oceanic ozone deposition through field measurements, modelling, and laboratory studies. Dry deposition of ozone to the ocean surface accounts for approximately one third of the total global dry deposition, with a high degree of uncertainty. Better constraint of this process has important implications for health, the oxidative capacity of the atmosphere, and quantification of the total global tropospheric ozone budget.

I have deployed a chemiluminescence ozone detector onboard research cruises for the measurement of open ocean shipborne eddy covariance ozone fluxes. These will be used to constrain a refined parameterisation representing the deposition process in global models. I am investigating the chemical drivers of oceanic ozone deposition through laboratory studies using a heterogeneous flow reactor. As part of my PhD, I will also assist in the development of a cavity enhanced UV-absorption ozone instrument suitable for deployment on aircrafts.
