I am a statistician working on Bayesian inference and applications, specifically theory and applications of Markov chain Monte Carlo (MCMC).
I am currently the Editor-in-Chief of The Canadian Journal of Statistics.

I am currently on sabbatical (until July 2014).

My main areas of applied interest are Here is a list of some recent publications (appeared/accepted 2007-2012:)
