Professional biography

I am an environmental microbiologist researching the habitability of martian environments, biogeochemical cycling of iron and associated metabolisms.

I received my PhD from the Open University, focused on characterising nitrate-dependent iron oxidation as a potential early Mars metabolism. This involved lab-based simulations of early martian chemical environments, investigated growth and biomineralisation on olivine and targeted the biochemical mechanisms of this metabolism through genomics and knockout mutants.

Current and recent projects involve Mars analogue fieldwork in the Makgadikgadi salt pans of Botswana, as well as Mars simulation studies.
