I am a Senior Lecturer in the Department of Mathematics and Global Systems Institute.

I have recently started in Exeter (in June 2020), following a PhD in Atmospheric, Oceanic, and Planetary Physics at Oxford, almost four years as a postdoc in the Department of Earth and Planetary Sciences at Johns Hopkins University, and 18 months as a research fellow in the School of Geographical Sciences at the University of Bristol (where I still have an honorary affiliation).

I am interested in understanding the large-scale dynamics of the atmosphere and oceans of Earth (and sometimes other planets too). I use a combination of idealised models, comprehensive general circulation models, and observational data. My current particular interests include:

  • Polar vortex dynamics on Earth,Mars, and Titan
  • Jet stream and Hadley cell variability
  • Stratospheric ozone depletion
  • Southern Ocean-atmosphere interactions

If you are interested in a PhD or Postdoc position in these or related areas, then please feel free to get in touch.

I currently have two fully-funded PhD studentship opportunities available. Do get in touch if you are interested in these opportunities. 
  1. On The Atmospheric Dynamics of Tropical Expansion, for which I'm the lead supervisor and Stephen Thomson is a co-supervisor. *Deadline: 24 January 2022*
  2. On Effects of rapid Arctic climate change on jet streams and extreme weather, for which Stephen Thomson is the lead supervisor, and I am one of the co-supervisors. *Deadline: 10 January 2022*
