Duncan J. Kountz studies the biochemistry of gut bacteria, focusing on how microbes use vitamin B12 (cobalamin) and metal-containing enzymes to break down and transform nutrients like choline, carnitine, and amino acids. This work combines microbiology, enzymology, and natural product discovery to understand how gut microbes generate unusual metabolites and support fermentation-based growth in the human digestive system.
Publication output has been fairly steady over the past five years, averaging about two papers per year after a gap earlier in the decade, with a slight uptick in preprints and journal articles in 2024-2026.
