Biography

Geochemical cycling of trace elements in natural and perturbed environments, particularly redox-sensitive processes affecting metals and metalloids. Applications to mine tailings, coastal sediment, estuaries, and groundwater, as well reconstructions of past climate change in nearshore environments. More recent interest in the bridging of disciplines, including the health and social sciences, to address multi-faceted environmental problems.

Some of my projects include:

  • Reconstruction of climate change along the west of coast of the Americas
  • Geochemistry of cadmium and iron in coastal upwelling systems
  • Mitigation of groundwater arsenic problem in Bangladesh
