Ralph R. Isberg (born January 3, 1955) is a professor at Tufts University School of Medicine[1] known for his contributions to understanding microbial pathogenesis.
A microbiologist, Isberg has published over 185 peer-reviewed articles[3] and is or has been an editor of the Proceedings of the National Academy of Sciences,[4] PLoS Pathogens, and Journal of Experimental Medicine, among others.
He performed his post-doctoral research in Stanley Falkow's lab at Stanford University (1984-1986), where he initiated studies of the entry of the bacterial pathogen Yersinia pseudotuberculosis into mammalian cells.
[1] He is also the co-director of the Center for Enteric Disease in Engineered Tissues (CEDET) and Program Director of Molecular Basis of Microbial Pathogenesis.
[5] His lab focuses on the pathogenesis of Legionella pneumophila and Yersinia pseudotuberculosis, especially the ways these pathogens enter and regulate host mammalian cells.
