Ocean Current Modelling - Physical Oceanography - Marine Plastic Pollution
My research focusses on understanding the connections between different parts of the ocean. Plastic debris, heat and marine organisms are all transported by ocean currents - understanding the time-scales and possible pathways of their motion is important for a range of academic and policy-relevant reasons. I use a range of models, mathematical techniques and instrument data to recreate the complexity of ocean motion.
Supervisors: Dr Arnaud Czaja (Imperial College London) & Dr Erik van Sebille (Utrecht University)
Topics of research:
- Transport Barriers and Connectors: Examining the role of the Agulhas Current and Gulf Stream in inter-ocean transport
- Detecting plastic hot-spots: Predicting accumulation regions of floating plastic waste
- Network theory and oceanography: Improving stochastic (Markov-chain) representations of current systems
- From surface to abyss: Exploring how inter-ocean connections vary with depth
Outreach & Education
I am very enthusiastic about sharing the results of scientific research to a wider community. See below for some of my work on public exhibitions, lectures and articles:

Pakeman Primary School Radio Interview
Articles for Significance Magazine
I also give frequent talks at school events, careers fairs and public lectures.
Secondment at the Royal Statistical Society
