Research summary

Dr. Armstrong’s research has helped identify how the hallmark dysbiosis in inflammatory bowel diseases leads to dysregulated fibre fermentation, increased interactions of unfermented fibres with immune cell receptors, and reduced beneficial fermentation byproducts (e.g., SCFAs), resulting in worsened inflammation in select patients.

Her team works to understand the mechanisms behind diet-associated inflammation in inflammatory diseases, mediated by gut microbes. This is particularly critical as the sustained inflammation in the gut of IBD patients is directly associated with increased risk of cancer and mortality.

Research affiliations


Dr. Armstrong is an assistant professor of internal medicine with the Rady Faculty of Health Sciences and a a research scientist with Children's Hospital Research Institute of Manitoba (CHRIM).  She is also research scientist with the UManitoba IBD Clinical and Research Centre and a founding member of the Manitoba MS Research Centre.

Past positions include a role as instructor for the University of Alberta School of Medicine and Dentistry.

Dr. Armstrong is passionate about mentoring and supporting young scientists who are interested in learning more about complex co-culture techniques for use in translational research approaches to personalized medicine.

She is involved in several national and international multi-disciplinary teams where she utilizes her translational models of microbiome and human biopsy tissues to better understand the pathology of diseases of dysbiosis, such as IBD, MS, and RA, and their relationship to cancer.
