My research explores the multi-disciplinary links between geochemistry, mineralogy, and microbiology in controlling environmental mobility and speciation of metalloids, such as antimony and arsenic, in soil-water systems. My discoveries have application in managing contaminant transport through landscapes, and in the remediation of soil and sediments with low-cost technologies. I am passionate about exploring the complex interactions between mineralogy, microbiology, and trace metalloid geochemistry using a wide range of advanced analytical techniques including X-ray Absorption Spectroscopy (XAS) to manage and remediate environmental contamination.

Research interests

  • Biogeochemical cycling of iron and sulfur in acid sulfate soil wetlands and acid mine drainage affected environments.
  • Transformations of minerals under fluctuating redox conditions.
  • Geochemical behaviour and redox transformation of trace metals and metalloids such as arsenic and antimony in soils and sediments.
  • Antimony speciation and fate in anoxic aqueous environments and its interactions with the sulfur cycle.
