Liam E. Rondeau is affiliated with McMaster University as a researcher in the Caminero Lab at the Farncombe Family Digestive Health Research Institute within the Department of Medicine. He completed a BHSc in Biomedical Discovery and Commercialization, with his undergraduate thesis conducted in the Verdu Lab involving an industry project with Nestlé. His research explores microbial metabolism of dietary components, including tryptophan metabolism, proteolytic activity, and allergen degradation, and its influence on host responses in conditions such as colitis, inflammatory bowel disease, and food allergies including peanut allergy. Rondeau utilizes mouse models of colitis, cell culture, and microbiome analysis in his work. Key publications include co-authored papers such as “Proteolytic bacteria expansion during colitis amplifies inflammation through cleavage of the external domain of PAR2” (2024) and “Microbial metabolism of food allergens determines the severity of IgE-mediated anaphylaxis” (2026), along with contributions to studies on dietary tryptophan and aryl hydrocarbon receptor activation in reducing intestinal inflammation. His doctoral thesis examined microbial protein metabolism in gastrointestinal and allergic inflammation.
