We study the physiology and biochemistry of deep sea microorganisms, with an emphasis on carbon and nitrogen metabolism, to better understand their role in mediating local and global biogeochemical cycles. We also study the physiological relationships (such as nutrient exchange and immune responses) between microbes and animals in natural systems. To that end, we apply traditional or modern geochemical and molecular technologies -and develop new technologies- to interrogate physiological and biochemical processes in natural systems or laboratory simulations.
