Dr. William Bishai is a professor of medicine at the Johns Hopkins University School of Medicine. He holds joint appointments in pathology and in molecular biology and genetics and, at the Johns Hopkins Bloomberg School of Public Health, in international health. His area of clinical expertise is infectious diseases. Dr. Bishai serves as co-director of the Johns Hopkins Center for Tuberculosis Research.
Dr. Bishai received his B.A. from Harvard University and an M.Phil. from Cambridge University. He earned his M.D. and Ph.D. from Harvard and completed his residency at the Brigham and Women’s Hospital. He performed his fellowship in infectious diseases at Johns Hopkins. Dr. Bishai was a Howard Hughes postdoctoral research fellow before he joined the Johns Hopkins faculty in 1994.
His research focuses on the molecular biology of mycobacterium tuberculosis.

Research & Publications
Dr. Bishai is interested in the molecular pathogenesis of tuberculosis. Since Mycobacterium tuberculosis senses and adapts to a wide array of conditions during the disease process, it is clear that the regulation of expression of virulence factors plays an important role in pathogenesis. Hence, a theme of his research has been to assess mycobacterial genes important in gene regulation.
Other active interests are cell division in mycobacteria and the pathogenesis of caseation and cavitation. The use of the mouse and rabbit models of tuberculosis has been a prominent aspect of these studies. Goals of the research program are first to better understand tuberculosis pathogenesis, and then to employ this understanding toward improved drugs, vaccines and diagnostics.
