Assistant Scientist
Julie Huber's CV >>
I am a microbial oceanographer interested in the ecology of bacteria and archaea in the deep sea, especially at underwater volcanoes. At these hydrothermal systems, warm fluids are leaking out of the crust, providing access to the subseafloor biosphere. Most of my research focuses on the oceanic crust as a microbial habitat and the distribution, diversity, and evolutionary and community dynamics of microbial groups in the subseafloor. Currently, I am using phylogenetic, metagenomic, cultivation-based, and geochemical measurements of deep-sea crustal fluids to link microbial groups with their metabolic and physiological functions in subseafloor habitats. Microorganisms from this environment offer opportunities to study many exciting aspects of marine microbial ecology, including molecular evolution, microbial diversity, astrobiology, biogeography, adaptation to high temperatures, and functional genomics of complex communities. I am broadly interested in marine microbial ecosystems of all types, from coral reefs to marine sediments, and the methods and approaches that unite microbial scientists. As a sea-going scientist, I am also interested in technology development for deep-sea exploration and in-situ experimentation.
