معرفی
William Brazelton is a Research Associate Professor at the Department of Biology, University of Utah, specializing in extremophilic microbial ecology. His work bridges geobiology and astrobiology through interdisciplinary studies of serpentinization-driven ecosystems like the Lost City hydrothermal field and terrestrial analogs in Newfoundland, Italy, and California.
- Education:
- Ph.D., University of Washington
- NASA Astrobiology Postdoctoral Fellowship
Research Interests focus on how serpentinization processes generate hydrogen and methane to sustain subsurface microbial life independent of photosynthesis. His lab employs metagenomic sequencing, biogeochemical measurements, and cultivation techniques to explore microbial metabolism in extreme pH environments.
Publications highlight patterns in microbial community adaptation to serpentinization byproducts, including hydrogen, methane, and carbon monoxide. Key findings include the dominance of Betaproteobacteria in oxic-anoxic transition zones and Clostridia in anoxic habitats, alongside novel hydrogenase and carbon fixation pathways.
- Scientific Awards:
- NASA Astrobiology Postdoctoral Fellowship
Grants include funding from the National Science Foundation, NASA Astrobiology Institute, and the Sloan Foundation’s Deep Carbon Observatory to support field expeditions like the 2018 Return to Lost City. His lab collaborates with institutions in the U.S., Canada, and Switzerland, maintaining active research observatories such as the Coast Range Ophiolite Microbial Observatory (CROMO).
