Research Profile

My research interests are broadly in the area of geological history, and more specifically are aimed at understanding the dynamics of major past perturbations in the Earth’s physical and biological systems and their expression in the sedimentary record. I employ a range of laboratory and field techniques at the interface of stratigraphy, sedimentology, isotope geochemistry, and palaeobotany. Most of my recent research has focussed on the mid-Mesozoic time interval, but I am interested in the record of past events through the whole of Earth history. Current research projects include a multidisciplinary and collaborative study of mudrock genesis and diagenesis funded by Shell.
