fecal microbiota transplantation gut microbiome recurrent Clostridioides difficile infection inflammatory bowel disease


The success of our research team in establishing a successful therapy for an extremely debilitating condition is one of the most gratifying aspects of my career. Diseases of the gut are prevalent, with the incidence of some conditions especially high in Alberta. Research is the best tool we have to identify potential new treatments to alleviate gastroenterological disease, such as recurrent Clostridioides difficile infection (rCDI). 

After receiving my medical degree from the University of Alberta, I completed residencies in internal medicine and gastroenterology at the University of Ottawa before returning to Edmonton. My interest in using data to improve clinical care led her to pursue a Master’s in Epidemiology from the University of Alberta. The challenges of treating patients suffering from severe gastrointestinal infections caused by rCDI inspired me to research the effectiveness of fecal transplantation as a therapy. I established the Edmonton Fecal Microbiota Program in 2013. The resounding success of this program has led to successful treatment—and recovery of health and well-being—in over 600 patients, and garnered national and international recognition for our team.


Our research program is exploring the therapeutic manipulation of gut microbiome through fecal transplant in rCDI and inflammatory bowel disease. We have several clinical trials actively recruiting patients to examine the clinical efficacy in these conditions. With international collaborators, we are investigating the mechanisms of action of FMT.
