While we continue collaborations focused on the role of the gut microbiota in shaping non-human primate ecology and evolution, our current research focuses on comparisons between non-human primates and humans as well as investigations of host-gut microbe dynamics in human populations around the world. These projects broadly examine the interactions of host diet, physiology and the gut microbiota. More specifically, we focus on microbial contributions to host nutrition during periods of reduced food availability (e.g. seasonality) or increased nutritional demands (e.g. pregnancy), as well as microbial influences on brain growth.
