Environmental Geochemistry and Geomicrobiology MPhil – (M.Phil.)

The overarching theme of the work of this group is the characterization of mineral-water-organic matter reactions in surface and near-surface environments. As chemical reactions in these environments are often catalysed by microorganisms, we have developed a recent and expanding interest in geomicrobiology. Here, by combining the techniques of microbiology and molecular biology with physical, chemical and modelling approaches, we are focusing on the role microorganisms play or have played in key geological processes.

Fundamental work in this group aims to identify the biogeochemical controls on mineral cycles in a range of environments; including the iron and sulfur cylces, as well as those of toxic metals including arsenic, chromium, technetium, and transuranics. This work is facilitated by excellent infrastructure to study the biological, mineralogical and geochemical components of such cycles at a molecular scale. Also under investigation are innovative approaches that can be used to guide natural biogeochemical cycles to drive the remediation of land and water contaminated by metals, radionuclides and toxic organics.
