I am a first year PhD student in the Atmospheric and Cloud Dynamics research group in the Institute of Climate and Atmospheric Science, funded by the SENSE Earth Observation CDT.

I graduated with an MEarthSci Earth Sciences degree from the University of Oxford in 2021. Here, I specialised in oceanography, climate and atmospheric science, mantle dynamics, and volcanology. My Master’s project aimed to provide motivation in using the moist static energy budget approach to analysing classic cyclonic processes in the Mozambique Channel. This was in order to understand and provide reasoning for deep convection biases in the Met Office convective-permitting climate simulation CP4-Africa, relative to its convective-parameterised counterpart R25-Africa, which had a pre-existing bias relative to observations. For this project, I was supervised by Dr Neil Hart from the Oxford School of Geography and the Environment.

After finishing my undergraduate degree, I moved to Leeds to begin my PhD in October 2021. I am supervised by Dr Juliane Schwendike, Dr Cathryn Birch and Dr Simon Peatman from the University of Leeds, as well as Dr Massimo Bollasina from the University of Edinburgh and Paul Barrett from the Met Office. I will be using a combination of satellite, ground-based radar, and in situ observations to study and better understand key atmospheric processes leading to the initiation and propagation of severe convective storms over the Maritime Content in Southeast Asia. In addition, I will investigate how low-frequency modulations of the background state (e.g. in wind and humidity), such as through the Madden-Julian Oscillation and annual cycle, impact convection in the region. I will also evaluate how numerical weather and climate models of varying complexity represent storm formation to study key processes beyond the limitations of the observations analysed.
