Profile

General Information

I am a Reader in Stratigraphy and teach primarily on the Palaeobiology and Evolution Degree course at 2nd and 3rd year level.

Teaching

I am the Unit Co-ordinator and lecturer for:

• Level 2: Vertebrate Palaeontology 1 and Traces to Humans (BGS280)
• Level 2: Palaeotechniques, Palaeobotany and Micropalaeontology (BGS279)
• Level 3: Palaeoecology (1GS376)
• Level 3: Biostratigraphy (2GS319)

Career History

• 1996 - Present: Reader, School of Earth and Environmental Sciences, University of Portsmouth
• - 1996: University of Aberystwyth

Professional Record

• Editor of Palaeontographical Society Monographs
• A member of the Editorial Board of Paläontologisches Zeitschrift and Geolines
• Titular Member of the IUGS Subcommission on Silurian Stratigraphy (SSS)
• Chairman of the Llandovery-Wenlock boundary working Group of the SSS
• Vice-President of the Palaeontological Association

Research

My research focuses on the Silurian System. Current projects are:

• Dating the hydrocarbon source rocks ('hot shales') in North Africa and the Middle East
• Attempting to improve correlation between deep and shallow water environments, mostly in Estonia and Latvia.
• Scanning Electron Microscopy (SEM) study of graptolites extracted from limestones and marls.
