Bayesian Statistics, specifically Change Point and Variable Selection algorithms.  A majority of my research has focused on studying a 5 million year record of the Earth's glacial activity.  Over the last 1 million years, the Earth's glaciers have been melting and reforming every ~100,000 years.  Prior to this time, glacial melting events occurred every 41,000 years.  The goal of my work has been to try and determine exactly when these changes have occurred and then fit an appropriate model in each climate regime.
