Age 34
I am a lecturer in mathematics at the University of Surrey in Guildford, England, where I have been working since January 2012. I live in London.

In general I am interested in applications of ergodic theory to other areas of mathematics. Some particular problems which interest me at the moment include the analysis of algorithms using Ruelle operators, the topological dynamics of control systems, and the joint spectral characteristics of sets of linear operators.
