About

Karen Guillemin studies how host-microbe interactions shape animal development and microbial community assembly. Her work explores how bacterial secreted products influence programs of proliferation and maturation in the intestinal epithelium, the innate immune system, and the pancreas. In parallel, her research explores how bacteria sense, navigate, and interact with host tissues. Her research group uses several gnotobiotic animal models for these studies, including zebrafish. Her group’s live imagining studies in zebrafish reveal how bacterial dynamics in the vertebrate intestine shape microbiota composition and host tissue responses.
