The Universe is a beautiful and fascinating puzzle. I am lucky enough to get paid for trying to explain how it works, and to model it mathematically. More about my work on non-equilibrium statistical mechanics can be found here and I discussed why it's fundamental here. An introduction to rheology (the flow-properties of fluids) and some of my work on that area can be found here. My publications are listed here.

Research projects available:

PhD project for a suitable candidate:
Evolutionary game theory of scarce resources

For Leeds Maths students, I am have the following short research projects available:

For MATH5003/4:
Modelling animal movement
The XY model: An idealized model of magnets and non-Newtonian fluids

For MATH3001:
Using random numbers to solve mathematics and physics problems


PhD projects I currently supervise:

Organisation of particles on curved surfaces (co-supervised by Dr Paul Clegg)
PhD student Jason Klebes

Statistical physics of biological evolution (co-supervised by Dr Sandro Azaele & Dr Mauro Mobilia)
PhD student Leonardo Miele

Microrheology of microscopically phase separated hydrogels (co-supervised with Dr Johan Mattsson)

Public Understanding of Science

As well as publishing in academic journals, I enjoy writing about all aspects of science, and giving public talks about my work and other developments in applied mathematics and theoretical physics.

In my blog PhysicsBloke.blogspot.com I talk about the elegant and awe-inspiring workings of nature, about my research, science and education policy, and more personal and whimsical views of physics and applied maths. I try to convince the readers that they don’t need to be Albert Einstein to understand the answers. I believe that no topic is too advanced to be explained in an entertaining way. So my articles are aimed at everyone. Curiosity is the only qualification that my readers need.

In a similar vein, I have written for the Institute of Physics and for BBC Sky At Night Magazine, where my series of feature articles, "The Big Questions", tackled the enduring questions about the universe. More details here.
