Bryan Crable received his master’s degree in Biology from Duquesne University and Ph.D. in Microbiology from the University of Oklahoma. Crable specializes in microbial physiology because he recognizes the essential role bacteria play in solving the world’s toughest environmental challenges. His doctoral dissertation was titled “Enzyme Systems Involved in Interspecies Hydrogen and Formate Transfer Between Syntrophic Fatty and Aromatic Acid Degraders and Methanospirillumhungatei.” This work demonstrated the role of a novel iron-sulfur (FeS) oxidoreductase complex in catalyzing reverse electron transfer. He was appointed in 2014 as an ORNL postdoctoral research associate under the mentorship of Dwayne Elias to study the native physiological function of HgcA. Crable is first author on a comprehensive invited review on mercury methylation for the journal Trends in Microbiology, first author on a paper published in Enzyme Research, and co-author on seven papers including a publication in Science Advances. In 2015, Crable gave an invited talk at the American Society for Microbiology general meeting and participated in the Applied and Environmental Microbiology Gordon Research Conference. Most recently, Crable was awarded a $130,000 grant (fiscal year 2016) from the Department of Energy-funded Ecosystems and Networks Integrated with Genes and Molecular Assemblies (ENIGMA) program to study the impact of phages on subsurface microbial communities. Outside the laboratory, Crable is an internationally competitive Highland bagpiper and has won awards in six countries.
