John Baross is a Professor in Oceanography and the Astrobiology Program at the University of Washington. He specializes in the ecology, physiology, and taxonomy of microorganisms from hydrothermal vent environments, and the use of biochemical and molecular methods to detect, quantify, and classify the same.
John has particular interests in the microbial ecology of extreme environments, the biotechnological applications of microorganisms that grow in extreme environments, astrobiology, and in the significance of submarine hydrothermal vent environments for the origin and evolution of life. The novel environment and microbes present at Lost City are of great interest to John and his laboratory group. Samples recovered from this field offer potential for new discoveries and insights into life in the extreme environments of hydrothermal vents.
