The deep-sea is the Earth’s last frontier of exploration; thus, my research interests are examining the activity and ecology of archaea and bacteria that colonise marine sediments. Deep-sea microbial communities play an important role in the biogeochemical cycling of major elements (such as carbon, nitrogen and sulphur). By investigating the activity and diversity of deep-sea microbes, and the variables that affect community structure, we can begin to predict how these ecosystems may shift in the face of climate change, and whether they will act in positive or negative feedbacks to rising ocean temperatures. Furthermore, examining the ecology and metabolic activity of modern deep-sea ecosystems, we can begin to untangle the complex interactions between marine microbes and their environments, and extrapolate these relationships into the geological past to understand the co-evolution of life and Earth’s surficial environment.
