The underlying theme of my research is to use microbiology (and in particular novel molecular techniques applied to microbial ecology, microbial biodiversity and activity, environmental genomics, biogeochemical cycling and model extremophiles) to understand Polar ecosystem function and the potential for shifts in biogeochemical activity that may result from environmental change. I have taken the lead in the development of new frontiers of research in metagenomics, chemosynthetic communities, sediment sequestration of carbon and subglacial lake environments and have initiated new interdisciplinary approaches on the aerial environment (with chemists), ice nucleation activity (with physicists) and in the biogeochemistry of ice (with glaciologists).
