Hung Ton-that

Biography

Dr. Ton-That obtained his Ph.D. degree from the University of California at Los Angeles (UCLA) in 2000, working with Dr. Olaf Schneewind to elucidate the mechanism of sortase-catalyzed cell wall anchoring of surface proteins in Staphylococcus aureus. He came to the University of Chicago for his postdoctoral training and became interested in pilus assembly in Gram-positive bacteria. Between 2004 and 2008, he held an assistant professor position at the University of Connecticut Health Center to continue his studies of Gram-positive pili and their role in biofilm formation and bacterial pathogenesis. In 2009, he joined the Department of Microbiology and Molecular Genetics at the University of Texas-Houston Medical School. His research program currently focuses on the molecular assembly on the cell surface of Gram-positive pathogens, oxidative protein folding in Gram-positive bacteria, and virulence mechanisms of the Gram-negative pathogen Fusobacterium nucleatum. His teaching duties include courses for graduate and medical students and directing a laboratory-based course in fluorescence and electron microscopy.
