John Pak, Ph.D.

Senior Scientist

John Pak received his Ph.D. at the University of Toronto, where he focused on elucidating the three-dimensional structures of glycoproteins, including that of the SARS spike antigen in complex with a neutralizing antibody fragment. As a postdoctoral fellow in the lab of Robert Stroud at the University of California, San Francisco, Pak’s work centered on the biochemical and structural characterization of bacterial and mammalian membrane proteins. At BioMarin Pharmaceutical, he led efforts to utilize experimental and computational structural biology to catalyze preclinical research across diverse drug modalities, including biologics, small molecules, and AAV gene therapy. At CZ Biohub SF, Pak has built a protein sciences group with robust biochemistry and structural biology expertise that works closely with the Biohub community to discover and characterize novel host cell, pathogen, and immune molecules.
