Research Interests Comparative physiology, biochemistry and ecology of microbial communities, with a focus on free-living syntrophic bacterial associations in extreme environments including hydrothermal vents and Antarctic soils. The use of high through-put genomic and molecular approaches to resolve biochemical adaptations to life in these extreme geochemical environments. Interfacing new bioinformatic capabilities with genomic technologies in the metagenome analysis of complex microbial communities. Thermal stability of eurythermal proteins.
