Jean-Philippe Julien

Julien is an internationally recognized leader in antibody structural biology whose laboratory elucidates the mechanisms of antibody action to guide vaccine and immunotherapy design. His research has translated seminal discoveries in structural biology, microbiology and immunology into advanced practical applications. In collaboration with academic and industry partners, Julien’s laboratory develops novel antibody-mediated immuno-modulatory approaches against tumor and autoimmune targets using structure-based principles.

In 2020, Julien co-founded Radiant Biotherapeutics—a pharmaceutical company built on the cutting-edge Multabody™ platform, a multi-specific, multi-affinity antibody technology that uniquely harnesses nature’s protein scaffolding principles to deliver next-generation therapies for hard-to-treat diseases, including cancer, auto-immune and infectious disease.

Julien’s work is published in leading journals, including Nature Communications, Science and Immunity. He has authored more than 115 peer-reviewed publications and contributed over 150 Protein Data Bank and over 75 Electron Microscopy Data Bank entries. He has been named to Clarivate’s Highly Cited Researcher list in microbiology, reflecting the sustained global impact of his research. Julien has delivered over 125 academic presentation and over 25 knowledge-translation and technology-focused talks, in addition to participating in interviews with media with outlets such as LA Times, CBC, and Radio-Canada.

His research program has received funding from NIH, CIHR, and international philanthropic foundations. Julien has an outstanding awards record, receiving 18 awards as a Principal Investigator. He has received prestigious honours, including a Tier 2 Canada Research Chair in Structural Immunology and election to the Royal Society of Canada’s College of New Scholars. Julien was named CIFAR Azrieli Global Scholar as well as one of Canada’s Top 40 Under 40 (2021), underscoring his broad impact on biomedical research and innovation.
