My work focuses on stress and the gut-brain axis. Previous research in the Gaultier lab has shown that stress can change the microbiome and induce depressive phenotypes in mice. However, how stress causes the microbiome to change is still unclear. One possibility is through a change in mucus composition. As mucus provides the niche for the microbiome to feed off of and live within and mucus production has been shown to change in times of stress, it has become a major research interest. My project focuses on how stress changes mucus composition within the mouse small intestine and how this change may impact the microbiome and depressive states.
