I'm a postdoc at the University of St Andrews working with Kenneth Falconer on various problems relating to dynamics on self-affine sets. This position is funded by the EPSRC.
Previously I worked with Karma Dajani at the University of Utrecht. The main focus of my research there was the ergodic theory of dynamical systems relating to expansions of real numbers. In particular, I looked at how properties of the random beta-transformation can be used in the discussion of Bernoulli convolutions. I completed my PhD at the University of Warwick in March 2011 under the supervision of Mark Pollicott. My thesis was on thermodynamic formalism for symbolic dynamical systems. |

In 2013 I taught the course Ergodic Theory, which is part of the masters program at Utrecht and also part of the Stochastics and Financial Mathematics masters. For details, please see the course page.

I also gave a masters course on topics in dynamical systems, information about the course including some material can be found here. In the academic year 2011-2012 I organised the Stochastics and Numerics seminar together with Inan Ates, details of the seminar can be found here.
