For prospective MPhys students
I normally run 2-3 MPhys projects at any given time. These are usually linked to our ongoing research, I prefer to make them "mini-PhDs", which is why I normally favour full-year projects. Available topics vary from semester to semester (following the natural flow of our research), but they all focus on the application of nonlinear dynamics, statistical physics and the theory of stochastic processes to the mathematical modelling and simulation of problems in complex systems. Past and present topics have for example included
- The dynamics of Minority Games
- Chaos in game theory
- Stochastic models of evolutionary processes
- Agent-based modelling of evacuation dynamics
- When symmetry breaks, how big are the pieces ? The dynamics of defect formation
- Stochastic processes on complex networks
You might also want to look at the web pages of the Complex Systems and Statistical Physics Group, in particular the section on our research interests.
For prospective PhD students in the area of complex systems
If you are interested in a PhD in the area of complex systems, then you might also want to look at the web pages of the Complex Systems and Statistical Physics Group, in particular the section on Postgraduate Opportunities, where you can find a list of potential topics. You can also contact me by email and come by to talk in more detail.
