Research interests

My research interests are in Late Quaternary geochronology, with specific interest in radiocarbon dating and tephrochronology, as well as broader aspects of Quaternary palaeoclimatology.

I specialise in radiocarbon dating and, in particular, radiocarbon calibration.

I am also interested in Bayesian statistical modelling of chronological data.
