Key Research Interests

  • Effects of ancient terrestrial organisms (e.g. microbes, fungi, primitive plants) on rock weathering, soil production, and
    on carbonate precipitation in soils, lakes, and marine environments
  • Marine carbonate depositional environments (e.g. coral reefs) and the causes of changes in types of organisms
    constructing reefs
  • Processes of fossilisation of life, including for example preservation of microbes in limestones of modern and ancient
    alkaline lakes
  • Evolution of the Earth System over geological time, using stable isotopes (C,O,S) and inorganic geochemistry
  • Microscopy, including ‘cutting edge’ optical and electron microscopy
