Hung Ton-That*
The laboratory primarily focuses on three major areas of NIH-funded research (pilus assembly, protein folding, and fusobacterial pathogenesis), aiming to elucidate the molecular mechanisms of pathogenicity by Gram-negative and Gram-positive pathogens. We employ a multidisciplinary approach combining classical and modern techniques that include bacterial genetics, various biochemical methods, electron microscopy, electron cryo-tomography, X-ray crystallography, biophysics, mass spectrometry, cell-based assays, and rodent models of infection, hence providing a rich training environment to the lab trainees.
