Biography

  • Present: Head of NERC Earth Sector Facilities (geochronology and isotope geosciences) on behalf of the British Geological Survey
  •  1996 : Joint appointment with the University of Leicester's Department of Geology and the BGS

Skills

  • Climate change and tectonics
  • Depleted uranium and human exposure
  • Environmental isotope geochemistry
  • Heavy metal pollution, isotopic studies of metal bioavailability in soils
  • Himalayan geology
  • Isotope geochemistry and mass spectrometry
  • Management of large research groups/facilities
  • N American Cordilleran geology
  • Nuclear chemistry and isotope synthesis
  • Precambrian geology
  • Tectonics, structure and evolution of the continental crust
  • U-Th-Pb geochronology

Research interests

  • Accessory minerals in metamorphism: reactions, P-T conditions, and isotopic systematics with applications to the Himalaya
  • Dating of Quaternary carbonate rocks by high precision U-Pb dating in archaeology, hominid evolution, climate archives
  • Development of improved biomarkers for Pb exposure in population epidemiology using biological materials and teeth.
  • Exhumation of ultra high pressure metamorphic rocks and its chronometry
  • Himalayan tectonic evolution and Neogene erosion, mainly Bhutan, Tibet, India, Burma
  • Innovations in chemistry and mass spectrometry in U-Th-Pb dating and other isotopic systems, including plasma multicollector mass spectrometry
  • Provenance of sediments and dust and applications to Neogene erosion and climate change
  • The Neogene rise of the Coast Mountains of western Canada as a contributing cause of Northern Hemisphere Glaciation
  • The measurement of U isotopes in environmental and biological materials (esp. human urine): assessment of exposure to depleted uranium in military conflicts.
  • U-Th-Pb geochronology applied to a wide variety of applications using accessory minerals and carbonate, mainly using LA-ICP-MC-MS methods.
