We are interested in understanding how microorganisms that reside in complex communities interact through the sharing of nutrients, and how these interactions shape the composition and function of microbial communities. Our major research focus is on the vitamin B12 family of molecules (corrinoids), nutrients that are synthesized only by a fraction of the bacteria that use them. We use molecular biology, genetics, biochemistry, and analytical chemistry to investigate how these cofactors are synthesized, used, and acquired by bacteria.
