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.
