Dr. Comstock’s laboratory studies abundant bacteria of the human intestinal microbiota. These bacteria are mutualistic in that they both receive and provide beneficial properties to humans. There is still very little known about these bacteria and how they interact with each other and with the host. The lab is interested in understanding general molecular and ecological properties of these bacteria that allow them to survive and thrive in the human gut. Studies are also aimed at community dynamics of the intestinal microbiota, and how the bacterial community is influenced by the other coresident members and external factors.

Dr. Chatzidaki-Livanis studies bactericidal molecules produced by abundant gut bacteria of the order Bacteroidales. These diverse molecules appear to be ubiquitously produced by these gut bacteria and they are studying their biological properties as well as their role in shaping the gut microbiota.
