Research interests / background

My primary research interest is on understanding the various geochemical processes in terrestrial and aquatic environments. I would also like to apply my knowledge to understand and to address the water quality hazards faced by both terrestrial and aquatic environments.

Key Research Interests:

  • Acid sulfate soils
  • Arsenic and other heavy metals in soil materials and plants
  • Effect of climate change on geochemistry of terrestrial environments
  • Nitrogen and phosphorus cycling in natural environments
  • Soil carbon and carbon cycling in natural environments
