My research focuses on the pathways, interactions and environmental regulation of microbial processes that control oceanic nutrient cycling. I am particularly interested in the oceans oxygen minimum zones, where oxygen has been exhausted and microorganisms switch to anaerobic metabolisms.
Oxygen minimum zones are of particular interest as they are predicted to expand and increase in frequency as a result of global warming and human perturbations. This research is carried out through a combination of field work, experimental work in the laboratory using biogeochemical and micromolecular biology methods.
