Jason S. McLellan, PhD, Professor of Molecular Biosciences and Robert A. Welch Chair in Chemistry at the University of Texas at Austin, is an internationally recognized leader in structural virology and the development of structure-based interventions for viral pathogens. His research has led to the development of the first FDA-approved vaccine for respiratory syncytial virus (RSV), and the stabilizing substitutions his laboratory designed for coronavirus spike proteins are found in all COVID-19 vaccines authorized for use in the U.S. His laboratory has expertise in the determination of viral protein structures as well as extensive experience in structure-based design and biophysical characterization of protein interactions. Dr. McLellan and his team work collaboratively with domestic and international investigators in academia, government, and industry.
