I work in the field of stochastic processes, and am particularly interested in the ideas of coupling and stochastic stability, and their application to perfect simulation. At present I am interested in understanding the differences (and similarities) between maximal couplings and optimal co-adapted couplings, and the repercussions that such observations may have for the design of MCMC and perfect simulation algorithms.

The common theme of most of my research is coupling. Coupling is a powerful technique, with applications in many areas of probability, as well as being an active area of research in its own right. I've also recently started to dabble with ideas concerning fish recruitment and network analysis. A brief description of some of the topics which are of particular interest to me at the moment can be found on my homepage.
