Philip M. Sherman, MD, FRCPC, FAAP – Senior Scientist

Dr. Philip Sherman is a Professor of Paediatrics, Microbiology (Laboratory Medicine and Pathobiology), Nutritional Sciences & Dentistry at The Hospital for Sick Children (SickKids), University of Toronto where he has been on faculty since 1984. He is the recipient of a Canada Research Chair (Tier 1) in Gastrointestinal Disease (2001-21).  His current research is funded by support from the Canadian Institutes of Health Research and Lallemand Health Solutions. Sherman was the Scientific Director of the Institute of Nutrition, Metabolism and Diabetes (CIHR-INMD, 2009-2017).

Research focus: The Sherman lab investigates how probiotics, prebiotics and micronutrients influence the onset and progression of inflammatory bowel disease (IBD). With the use of in vitro models of bacterial infection and in vivo animal models of IBD the team is able to study the mechanism by which these factors influence disease outcome. The lab has been fortunate to see our work extend from basic research to clinical trials in both children and adolescents.

Shaiya Robinson, PhD – Postdoctoral Research Fellow


2009-2017 – Doctorate, Molecular and Cell Biology, McMaster University, Hamilton, ON

2004-2009 – Honours Bachelor of Science, University of Toronto, Toronto, ON

Research Interests: Investigating the molecular and biological outcomes of probiotics on homeostasis of the intestinal epithelium. Probiotics are bioactive beneficial bacteria that restore microbial balance, or homeostasis, in the intestine. In addition to regulating intestinal bacterial populations, probiotics also affect the intestinal mucosa. My research seeks to elucidate the molecular and biological mechanisms by which probiotics elicit changes (e.g. barrier function, immune responses, epithelial repair) in the intestinal epithelium.

Rachael Horne, MSc –  Research Technician


2016-2018–Master of Science, Neuroscience, McMaster University, Hamilton, ON

2012-2016– Honours Bachelor of Science, Biochemistry and Biotechnology, Wilfrid Laurier University, Waterloo, ON

Research Interests: My interests include the gut microbiota, Data analysis and host-microbe interactions. I utilize key data analytical skills, developed while studying gut-brain interactions, to explore how alterations in microbiota composition caused by inflammatory bowel disease are affected by treatment with probiotics and other micronutrients.
