Brian Dixon

Brian Dixon serves as Professor and Canada Research Chair in Fish and Environmental Immunology at the University of Waterloo, with dual affiliations at the Water Institute and Centre for Bioengineering and Biotechnology. His research bridges fundamental immunology with practical aquaculture applications, focusing on environmental impacts on fish immune systems.

Education:

• Bachelor of Science (BSc) from Wilfrid Laurier University
• Master of Science (MSc) from University of Guelph
• Doctor of Philosophy (PhD) from Dalhousie University

Research Focus: Dr. Dixon's work centers on fish immunological mechanisms under environmental stressors like temperature fluctuations, pollutants, and pathogens. His lab pioneers studies on probiotic applications, neuropeptide immunomodulators (PACAP), and innate immune pathways in salmonids and crustaceans. Key innovations include developing fish cell lines for in vitro disease modeling and exploring ploidy effects on immune competence in aquaculture stocks.

Publication Trends: Recent work (2023-2025) reveals three dominant trajectories: (1) advanced delivery systems for immunostimulants using phytoglycogen nanoparticles and encapsulated probiotics; (2) cross-species comparative immunology extending from salmon to shrimp and tilapia; and (3) One Health integration examining human-microbe-environment interactions. Over 70% of current publications employ in vitro models to dissect molecular mechanisms while reducing live animal use.

Honors:

• Canada Research Chair in Fish and Environmental Immunology

Academic Leadership: As principal investigator, Dixon directs the NSERC CREATE FishCAST program training next-generation fisheries scientists. His lab maintains active collaborations with Global Affairs Canada and aquaculture industry partners for vaccine development and disease management solutions. Current grants focus on climate-resilient aquaculture and sustainable immunostimulant deployment.

Research Infrastructure: The Dixon lab operates specialized fish cell culture facilities within Waterloo's Biology Department, including temperature-controlled systems for studying thermal stress responses. His team contributes to the university's Water Institute through interdisciplinary projects on aquatic pathogen dynamics and environmental immunotoxicology.
