In 2018, I graduated with a upper second class honours MChem degree having also completed a study abroad year at the National University of Singapore. My masters project was undertaken in the Heard group where I studied the atmospheric chemistry of free radicals in Beijing. This involved analysis of field data, atmospheric modelling using the Master Chemical Mechanism and experimental investigations into the heterogeneous production of HONO on illumimated aerosol particles. 

I am currently in my first year of my PhD studing the heterogeneous chemistry of reactive species on aerosol surfaces. Going forward with my PhD, I will be looking at the uptake coefficients of HO2 and RO2 radicals onto atmospherically revelent aerosol surfaces. I will be measuring the rate of production of HONO, OH and HO2 radicals on illuminated aerosol surfaces and will also be quantifying the impacts of HO2/RO2 uptake on aerosols using both zero-dimensional box models and the WRF-Chem and UM-UKCA global models.
