I work on enhancing methods to build chronologies for cores from deposits such as lakes, peat bogs and oceans, both using classical and Bayesian approaches. Part of this research concerns enhancing our understanding of the chronological uncertainties (precision, accuracy, reliability) of our reconstructions of past environments and climates.

Secure chronological contexts are essential for all research in palaeoecology and archaeology. I apply Bayesian chronological techniques through many collaborations throughout the world.
