# Research

I am interested in the application of Bayesian and Markov-chain Monte-Carlo techniques for modeling complex spatial/temporal systems. I am also involved in several interdisciplinary research projects involving the application of general linear models, linear mixed models, survival analysis and multivariate techniques to areas including: oil industry problems, magnetic reversal, plant science, drug and alcohol abuse, marine environment, animal behaviour, biogeographical data and change blindness studies (see if you can spot the changes in the image of me at the bottom of this page).
