Research themes
Microbial reduction of iron
Fundamental studies on the mechanism of electron transfer to insoluble Fe(III) oxides, and the impact of such transformations in a wide range of environments.
Biotechnological potential of nanobiominerals
Characterization of the molecular structure and properties of biominerals and their commercial potential.
Biogeochemistry of arsenic
Understanding the role of microorganisms in the mobilization of arsenic in aquifers and other environments, and identifying biotechnological approaches for the remediation of arsenic contaminated waters.
Bioreducation of azo dyes and pigments
Using Fe(III)-reducing bacteria to clean-up waters contaminated with problematic organics including textile dying waste-waters containing highly coloured azo dyes.
Biotransformations of radioactive elements
Addressing the impact of microorganisms on the solubilities of key radionuclides, for safety case assessments and bioremediation.
Geochemistry of evolving catchments
River catchment basins continuously evolve as rainwater, living organisms and rock-forming minerals interact chemically and physically to produce the soil profiles that cover most of the land surface.
Biogeochemistry of trace metals in marine environments
Aiming to understand how microbial interactions with trace elements, especially iron, control key biogeochemical processes.
