Ted Flynn

Assistant Microbial Ecologist

Biography

Dr. Flynn is a geomicrobiologist working in the Biosciences Division who specializes in understanding the links between microorganisms and biogeochemical cycles. His academic training was a combination geochemical modeling and hydrogeology with molecular microbial ecology, metagenomics, and microbial physiology. His research focuses on the biogeochemical cycling of elements, particularly Fe, S and C, and the ecological mechanisms that control the structure and function of microbial communities in such diverse environments as aquifers, wetlands, and the mammalian gut. 

Dr. Flynn came to Argonne in 2011 as a Director’s Postdoctoral Fellow in the Molecular Environmental Science group working with Dr. Ken Kemner and Dr. Ed O’Loughlin. Following his postdoctoral fellowship, he joined the Computation Institute at The University of Chicago as a researcher while continuing his work at Argonne with both the MES group as well as Dionysios Antonopoulos’ Microbial Systems group. As an Argonne staff scientist, he collaborates with these and other members of the Argonne Biosciences Division such as Jack Gilbert. 

Dr. Flynn is an expert in molcular microbial ecology and has extensive experience in both laboratory work (extraction of DNA from diverse environmental matrices, PCR, and high-throughput DNA sequencing) as well as computation (phylogenomic analysis of amplicon and whole-genome shotgun sequence data, metagenomics, genome assembly, and multivariate statistical analysis of large microbial community datasets). He also has expertise in geochemical modeling, cultivation of aerobic and anaerobic bacteria, and analytical geochemistry. 

Dr. Flynn is currently an editor for the journal mSystems, published by the American Society for Microbiology. He is a co-organizer of the 2014 and 2018 Midwest Geobiology Symposium and is a member of the American Society for Microbiology, the American Geophysical Union, and the Geochemical Society.
