There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Summary Sentence: "Deciphering the Deep: Microbial 'Dark Matter' Under the Sea" - Jennifer Glass, Ph.D. - Georgia Tech
Full Summary: The Petit Institute Breakfast Club seminar series was started with the spirit of the Institute's interdisciplinary mission in mind and started to feature local Petit Institute faculty member's research in a seminar format. Faculty are often asked to speak at other universities and conferences, but rarely present at their home institution, this seminar series is an attempt to close that gap. The Petit Institute Breakfast Club is open to anyone in the bio-community.

Research interests in the Glass Lab integrate field and laboratory studies to explore connections between major and trace elements in biogeochemical cycles. The major focus of our research is characterizing novel biological and abiotic mechanisms of greenhouse gas cycling via interdisciplinary studies merging geochemistry and molecular biology.
A primary goal of the lab’s funded projects is illumination of previously uncharacterized microbial aspects of methane production and consumption. Microbes are responsible for the majority of methane cycling on Earth, and methane-based metabolisms may have sustained ancient ecosystems prior to oxygenation of Earth’s atmosphere. Ongoing research is focused on elucidating microbial mechanisms of methane cycling in sediments from a tropical lake and the marine deep subsurface.
The lab is also probing mechanisms and environmental controls on globally significant pathways in the nitrogen cycle, namely coupled biotic-abiotic nitrous oxide production in the modern and ancient ocean, and environmental controls on microbial nitrogen fixation in boreal peatlands. We are also investigating the influence of oxygen on microbial iron usage in low-oxygen marine ecosystems and bacterial ribosomes.
