Areas of Interest

Geochemistry; environmental and clay mineralogy; nanogeoscience


My students and I investigate the influence of nanoscale materials and processes on the chemistry of environmental systems. We undertake studies to:

  • understand how size-dependent properties of nanoscale minerals influence natural and human-impacted environmental biogeochemical processes,
  • understanding the roles of nanoscale biogeochemical processes in mediating toxic element/compound release or sequestration, in order to
    • support sustainable water resources and practices and
    • create knowledge that aids in the interpretation of Earth’s geologic record, and
  • create new nanoscale solutions to emerging challenges at the intersection of Earth’s dynamic processes, natural resources, and human society.
