Climate change - Using a wide-range of deposits, especially stalagmites from caves, but also bone, coral and sediments, to obtain high-resolution records of past temperature, sea levels, vegetation change, faunal evolution. 

Geochronology -High-precision dating techniques to obtain chronological control on change in the Earth System (principally uranium-series and radiocarbon methods).

Environmental radioactivity - Developing novel protocols to explore source and pathways of radionuclides, particularly caesium, plutonium and uranium.
