Member of both the Bristol Research Initiative for the Dynamic
Global Environment (BRIDGE) and the Bristol Isotope Group (BIG).
Main research interests are
1. Quaternary climate change - using speleothems in particular, but also other archives such as bone, coral, ocean crusts, to obtain high-resolution records of past temperatures, sea levels, vegetation change etc.
2. High-precision dating techniques to obtain chronological control on change in the
Earth System (mostly U-series and radiocarbon methods)
Convene/teach Research Methods in Physical Geography (Yr 2) and
Quaternary Records (Yr 3), and lead the Mallorca field-trip
Member of editorial team for new Elsevier journal Quaternary Geochronology
