Research Interests

Our research is inspired by the spectacular diversity of microbes and gene products that have come to light in the post-genomic age. Microbial life has adapted to every imaginable environmental niche –  from the human gut to the hot spring –  in part by evolving an array of protein-based catalysts. Our longstanding expertise is with biocatalytic processes exploiting atmospheric oxygen and its partners – iron, heme, copper, organic cofactors, or sometimes just a protein environment alone. These carry out reactions that may be essential for bacterial pathogenicity, or which can solve economically important problems in a chemically green way. We likewise are focusing on microbial reactions that couple a redox step to the release or fixation of atmospheric carbon dioxide gas.  Studying these catalytic processes has led us to fundamental discoveries about how microbes interact with their environments to acquire and repackage the iron and heme that drive their redox “engines”.
