- Overview
-
The human gut is a very complex system that affects many areas of health. For the gut to work normally, there must be coordination between the immune system, nervous system, and multiple different cell types that line the gut and help it to process and absorb food while fighting infections. The gut also carries a huge number of microbes that play important roles in maintaining its functions. My work focuses on the way that the intestinal immune system functions to fight infections while maintaining normal relationships with the "good" bacteria that normally live in the gut.

Current Projects
My current research program targets two very important intestinal diseases: C. difficile infection and inflammatory bowel disease. C. difficile is the leading cause of hospital-acquired infections in Canada, and can lead to debilitating or even fatal diarrhea. I am exploring the role of the immune system in protecting against C. difficile by studying specific types of immune responses in people with their first episode of infection and comparing them to people with recurrent infections. I also have several clinical projects examining the benefit of fecal microbial transplantation (FMT), also known as "stool transplant", to control these recurrent infections.
My second main project is to develop a new treatment for inflammatory bowel disease (IBD; ulcerative colitis and Crohn's disease) based on the realization that people with these diseases develop abnormal immune responses to normal gut bacteria. It is believed that these responses "trick" the gut into thinking there is a bad infection, so it mobilizes its "army" of white blood cells into the gut, leading to unwanted inflammation that damages the gut. We are working to take advantage of these abnormal responses by making "super-suppressor" cells that reduce inflammation when they sense a major bacterial protein, flagellin, which is present in large amounts in the gut. We are also examining the types of immune responses that people with IBD make against flagellin to better understand how they cause damage.GrantsCanadian Institutes of Health Research (CIHR) Project Grant 2017-2021
