معرفی
Dr. Stephen Tuffs is an Assistant Professor in the Department of Biochemistry and Microbiology at the University of Victoria (UVic), Faculty of Science. His research focuses on host-pathogen interactions, particularly Staphylococcus aureus and its inflammatory mechanisms. He leads the Tuffs Lab, which employs bacteriological, immunological, and biochemical techniques to study bacterial toxins like superantigens and their impact on host immunity.
Dr. Tuffs holds an MSci (Hons) from the University of Glasgow and a PhD from the University of Edinburgh. His work has led to publications in high-impact journals, including Nature Reviews Immunology and Infection and Immunity.
Research Interests: His lab investigates how pathogens exploit inflammation to enhance survival. Key areas include superantigen-induced T cell activation, bacterial persistence in surgical infections, and the interplay between Staphylococcus aureus and vaginal microbiota. Recent studies highlight the role of glucose regulation in toxin production and the influence of bacterial metabolites on pathogenesis.
Lab Activities & Grants: The Tuffs Lab secured NSERC Discovery Grant funding in 2024 and collaborates with groups like the Goncheva Lab. Dr. Tuffs also engaged in policy advocacy via Science Meets Parliament BC in 2024. Current projects involve 3D bioprinting for wound models and studying Streptococcus pyogenes niche adaptation.
Lab members include students Silken Tschofen, Theresa Kelly, and Margaret, with recent awards such as the Canadian Society of Microbiologists Undergraduate Award. The lab emphasizes interdisciplinary approaches to combat bacterial infections and improve clinical outcomes.
