Dr. Julien Lab focuses on the molecular understanding of glycoproteins associated with immune function, providing roadmaps for the design of improved vaccines and immunotherapies for cancers and autoimmune diseases. The lab seeks to discover the mechanisms of action of antibodies at an atomic level, understand molecular interactions involving immune receptors, and apply integrative structural biology to design and characterize vaccines. Additionally, the lab engineers nanoparticles that are recognized by cellular receptors, contributing to advancements in immunological therapies and vaccine development.
