Our research interests:

Adaptations of marine microorganisms (from Bacteria, Archaea and their viruses to sea-ice algae (See Krembs et al, 2011 ) to life within physical support structures (frost flowers [See Bowman and Deming, 2010] shown above on the right, sea ice, particle aggregates and sediments), especially as they influence carbon and other elemental cycles. Listen to an interview on Quirks and Quarks, CBC radio (scroll to “Algae Architects”).

Cold adaptation in marine microorganisms and relevance to polar geochemistry and ecology (International Northwater Polynya Study, NOW; Canadian Arctic Shelf Exchange Study, CASES; Nansen Amundsen Basins Observational System, NABOS; Canadian Flaw Lead System Study, CFL)

Limits of microbial life, especially in ice, as they relate to astrobiology (UW Astrobiology Program), biotechnology (see genomic information for our model psychrophile at TGIR web site) and bioremediation (UW Marine Bioremediation Program). See some of our most recent work at the UW School of Oceanography’s “Life in Extreme Environs” link at the School’s Interdisciplinary Studies/Research page.

Role of benthic bacteria in biogeochemical cycles and ecosystems, from coastal to deep-sea environments (DGoMB)

Hydrostatic pressure in the evolution and ecology of marine bacteria, especially at very cold (in deep-sea and polar environments) and hot (at hydrothermal vents) temperatures.  See Tamburini et al., 2013, in Environmental Microbiology.
