Biography
I am a sedimentary geologist and geochemist. I am enthusiastic about both my teaching and my research. During my career I have worked on rocks from every continent and most geological time periods(ranging in age from the Precambrian to the Recent!).
Research Interest
I am interested in using stable isotope geochemistry, along with broader geological information, to solve interesting problems that help us understand how the earth works. My publications include work on past climates and environmental change: from relatively recent times (post-glacial records from lake sediments) to events associated with mass extinctions in the distant past. I also apply the same approaches to trying to understand hydrocarbon reservoirs. The geochemical records of environmental change in carbonates enable us to help to correlate between wells, understand both the internal architecture of the reservoirs. Our isotopic data also help us to work out the origins of mineral cements that block pore spaces in the rocks.
