Martin J. Blaser, M.D., is Chairman of the Department of Medicine at New York University School of Medicine, the Frederick H. King Professor of Internal Medicine, and a Professor of Microbiology. Dr. Blaser is interested in understanding the relationships between persistently colonizing bacteria and their multicellular hosts. His work has largely focused on Helicobacter pylori and Campylobacter species, which are important as pathogens and as model systems. Recent approaches have dealt with genetic and mathematical analyses of population diversity and structure. Recent work has focused on signal transduction pathways affected by intracellular delivery of H. pylori virulence-proteins (CagA and VacA).


Dr. Blaser is the Founder of the Virtual Museum of Bacteria, an online resource aimed at both scientific professionals and laypersons to aid in the study of bacteria. He also is the Publisher of the Bellevue Literary Review, a literary journal of poetry and prose published by NYU’s Department of Medicine from its offices at Bellevue Hospital.
