Department Profile

Teaching

I provide lectures and tutorials on early history of the Solar System, basic aqueous chemistry, radiogenic isotope geochemistry, and mathematical methods in Earth Sciences.

Research

My research has been focused on understanding a range of processes in the Earth Sciences using trace element distributions and isotope ratios, both with laboratory measurements and quantitative models. This includes research in:

  • The origin of volatiles in the terrestrial planets and their distribution within the Earth;
  • Weathering, water-rock interaction, and aqueous transport;
  •  The geochemistry of the Arctic Ocean;
  • The geochemistry of the Lena River of eastern Siberia which drains a vast area underlain by permafrost subject to substantial changes during climate warming;
  • The isotopic changes in trace elements due to weathering, water-rock interactions, and microbial processes, as the basis for developing methods for tracing environmental processes;
  • The reconstruction of paleoenvironments in depositional basins.

I am coordinator of the EC Marie Curie Initial Training Network MetTrans (Metal Transport in the Environment).
