I am a Reader in Stratigraphy and teach primarily on the Palaeontology BSc degree course.

My research focuses on the Silurian System, often using graptolites to date major biotic, environmental and tectonic events and also to date hydrocarbon source rocks.

Prior to moving to Portsmouth in 1996, I was at the University of Wales, Aberystwyth where my interest in the Lower Palaeozoic commenced.
