Research Expertise: Physical sedimentology and the influence of climate on continental sedimentary systems, Permian to Jurassic evolution of East Greenland and the North Atlantic, the Triassic of the North Sea.

Research Profile: My research interests are focused on climatic influences on sedimentation in continental settings. Lakes provide particularly high resolution depositories of environmental and climatic change. My work can allow us to examine climatic trends and understand global climatic systems back through earth history. Wider application of this research to climatic and tectonic signals recorded in a regional context is important in correlation and the prediction of facies distribution within continental settings and is therefore significant for hydrocarbon exploration.

Research into the sedimentological records of environmental change across some of the greatest extinction events (P-T & T-J) to affect life on Earth has augmented my research interests.

I have a broad background in field sedimentology and have spent extensive time working on the Devonian and Torridonian (Proterozoic) of northern Scotland and Orkney.  I have also spent 11 field seasons in East Greenland, working on the Mesozoic succession between 70o and 76o north, examining the evolution of sedimentary systems and the basins in which they were deposited.  More recently I have worked on the offshore Triassic of the Central North Sea and the PETM record penetrated in the Boltysh Impact Crater (Ukraine).

Teaching:  I am module leader of Sedimentology & Stratigraphy (CSM2183) and Dynamic Climates of the Past (CSM3060) and also contribute to teaching on Geology (CSM1030) and Enviromental Geochemistry (CSM1031).
