Dr. Teske’s research are is microbial ecology and systematics. He is particularly interested in bacteria and archaea of extreme marine environments, their natural diversity, their environmental tolerance and physiology. His most recent projects focus on the microbial community structure of hydrothermal vent sediments and chimneys, and of deeply buried sediments in the central oceanic basins and continental margins, using molecular and cultivation approaches. Microbial life in the ocean is extremely diverse and includes numerous phylogenetic lineages of bacteria and archaea that have not yet been cultured in the laboratory. He is planning to expand his research program towards physiology and ecology of uncultured microorganisms, using biogeochemical methods (diagnostic biomarkers, isotope studies) and genomic approaches, for example the analysis of key genes of specific metabolic pathways, or sequencing of large genome fragments from novel, uncultured microorganisms in extreme environments.
Recent projects include
- NSF-Biological Oceanography: Microbial Carbon and sulfur cycling in the hydrothermally heated sediments of Guaymas Basin. P.I., A. Teske, Co-PIs, C.S. Martens, D. Albert, B. MacGregor (06/01/07-05/31/12). This Project occurs in Guaymas Basin, a deep-sea hydrothermal vent site in the Gulf of California, Mexico, and in Chapel Hill.
- NSF-Microbial Observatories Collaborative Research: A Microbial Observatory examining Microbial Abundance, Diversity, Associations, and Activity at Seafloor Brine Seeps. UNC P.I. A. Teske; Univ. of Georgia P.I., S. Joye (Proposal P.I.); Texas A&M P.I., Ian MacDonald (08/01/08-11/30/13). This Project occurs in the Gulf of Mexico at several research sites from Texas to Mississippi, in Chapel Hill, at UGA and FSU.
- Gulf of Mexico Research Institute ECOGIG – Ecosystem Impacts of Oil and Gas Inputs to the Gulf. PI: Andreas Teske, Co-PIs: C.S, Martens, B. MacGregor, C. Arnosti (09/01/11-08/31/14). This Project occurs in the Gulf of Mexico, esp. at the Deepwater Horizon accident site and surroundings, at UNC in Chapel Hill, and at 14 collaborating institutions within the ECOGIG consortium.
