Our research investigates environmental microbial (prokaryotic) activities particularly in near and subsurface sediments. These two environments have vastly different rates of microbial activities, with rapid recycling of organic matter and nutrients in surface sediments to very slow �geological� activities (100- 1000�s years), with extraordinary low energy flux, in deep sediments. However, both of these activities exert control on global biogeochemical cycles and Earth�s chemical steady state, such as nutrient release for continued photosynthesis and organic matter burial which results in excess oxygen in the atmosphere. In addition, organic matter preservation and alteration provide the feedstock for oil and gas formation, and especially as temperatures increase, �dark energy� for sedimentary bacterial processes to kilometre depths. This biosphere:geosphere interaction continues into very hot deposits (>100�C) and include processes previously thought to be purely thermogenic (e.g. oil and gas formation). Many microbes in marine sediments are only known from their DNA sequences and a focus of our research is to discover their metabolism and environmental function.
A minimum 2.1 Honours degree or equivalent is required in Earth, ocean and planetary sciences, chemistry and physics.
