  • 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 flows of granular materials. I am particularly interested in currents 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, and they can be described by 'shallow water'-like equations. However, granular flows have more complicated dynamics, which are not captured by 'shallow water' models. There are no universally valid (or accepted) equations of motion.

I use a combination of pen-and-paper modelling and analysis, and discrete particle simulations.


I have supervised various courses in the Mathematical Tripos. Most of my students are from Queens', although I supervise for other colleges as well.

  • 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
  • Michaelmas 2017: Variational Principles

Please contact me if you would like me to supervise your students in these or related courses.

Other mathematical activities

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.
