Biographical details

I am a low-temperature environmental geochemist with expertise in chemical sedimentology and mineralogy. The mineralogical and biogeochemical signatures recorded in sediments tell us a story about Earth surface processes, environmental perturbations and past environmental conditions. My research teases apart these signatures in coastal, estuarine and marine systems, to better understand the complex interactions that shape natural processes at the Earth’s surface, and the impact that humans have on these.

Research interests

Some of my specific research interests include:

  • Exploring minerals as contaminate traps, including:

(a) Capture, storage and long-term security of CO2 in carbonate minerals.

(b) Mobility, bioavailability and toxicity of trace metals in natural and disturbed sediments and soils.

  • Formation, transformation and oxidation chemistry of sedimentary sulfides.
  • Biogeochemical element cycling during sediment diagenesis.
  • Coastal acid sulfate soils: Chemical processes, environmental impacts and remediation strategies.
  • Rare earth elements signatures as tracers of biogeochemical processes and anthropogenic influences.
  • Untangling the intricate associations between carbon, sulfur, iron and trace element cycles during formation and early diagenesis of coastal estuarine and marine sediments.
