Dr. Graham Benham

I am a post-doctoral researcher in fluid dynamics at LadHyx, École Polytechnique. I am part of the Sports Physics resarch group, working with Christophe Clanet and Michael Benzaquen on finding the optimum shape of rowing, kayaking and canoe boats.

I am interested in a variety of problems in fluid dynamics, with applications in sports physics, renewable energy, and industrial processes. My research combines a variety of analytical (mathematical modelling, asymptotic analysis), numerical (computational fluid dynamics, optimisation methods), and experimental (particle image velocimetry of turbulence) techniques.

I completed my DPhil in Mathematics (InFoMM CDT) at the University of Oxford, where my research project, in collaboration with VerdErg Renewable Energy, studied energy extraction in rivers.

Here is my CV.

Currently living in Paris.
