  • October 2015-present: PhD candidate, supervised by Nathalie Vriend and Stuart Dalziel.
  • 2014-2015: Part III of the Mathematical Tripos, University of Cambridge. 
  • 2011-2015: Mathematical Tripos, Queens' College, University of Cambridge. 


I am a member of the granular mechanics research group. I am funded by EPSRC, and supervised by Dr Nathalie Vriend and Prof Stuart Dalziel.

My research is on gravity currents of granular materials, and I am particularly interested in flows over topographical features, including dams, weirs and other devices that are used in defence against landslides. Granular gravity currents have some similarities to gravity currents in water: for example, they can form hydraulic jumps and drops, and waves can form on their surface. However, granular flows have much more complicated dynamics than water flows, and behave more like a shear-thinning fluid; their equations of motion are rather more nonlinear than the Navier–Stokes equations, although the two systems have similar structures.

I use a combination of asymptotic analysis and discrete particle simulations.


I supervise various courses in the Mathematical Tripos:

  • Michaelmas 2015: Dynamical Systems and Integrable Systems
  • Lent 2016: Electromagnetism, Fluid Dynamics I, and marking for part of Perturbation Methods
  • Michaelmas 2016: Variational Principles and Quantum Mechanics
  • Lent 2017: Electromagnetism and Fluid Dynamics I

Most of my students are from Queens', although I supervise for other colleges as well. Please contact me if you would like me to supervise your students in these or related courses.

Other activities

I am currently on the committee of the Emmy Noether Society.

I am a member of Queens' College and was a founding member of the Queens' College Mathematical Society during its (re)foundation in 2014.

I am regularly involved with outreach activities both for the Faculty of Mathematics and at Queens'. These include open days and Easter/summer schools (taster courses for sixth form students, which are free of charge for eligible students). In 2016 I helped at the Teach First Futures Easter School and the Sutton Trust Summer School.
