Infectious Diseases

  • David M. Markovitz, MD, Professor, Division of Infectious Diseases
    • Dr. David Markovitz is a Professor of Internal Medicine in the Division of Infectious Diseases at Michigan Medicine, who also has appointments in the programs in Cellular and Molecular Biology, Cancer Biology, and Immunology. Dr. Markovitz's laboratory focuses on understanding how human cellular factors control the replication of viruses, and retroviruses in particular. These studies are performed both to understand the biology of viruses and to develop possible therapies for these important human pathogens, as well as to exploit the viruses as a mechanism for understanding human cellular biology and cancer. In pursuit of the latter, his group has made important contributions to understanding how the DEK protein functions in health and disease, and he has developed a therapeutic agent that targets DEK to treat arthritis. More recently, studies of retroviruses led the group into centromere biology and the realization that centromeres are damaged in scleroderma. Dr. Markovitz’s work has been recognized by his election to the two principal honorary societies for academic Internal Medicine physicians, the American Society for Clinical Investigation and the Association of American Physicians, as well as to the American Clinical and Climatological Association. In addition to his research, Dr. Markovitz was a consultant on the Infectious Diseases service for many years and now attends on the inpatient general Internal Medicine service at Michigan Medicine. He has been married to Ruth Hurwicz Markovitz for 39 years, and they have three wonderful [adult] children, Lara, Rebecca, and Adam, and three grandchildren. Dr. Markovitz has a wide range of non-medical interests, and majored in Middle Eastern Studies as an undergraduate. He has a long-time interest in art, music, movies, novels, sports, and both serious and junky TV. Dr. Markovitz has traveled widely, and speaks 3½ languages.
