MARKET CORNER CONVERSATIONS: Dr. Jonathan M. Zenilman, Johns Hopkins University

Hear how Dr. Zenilman’s residency at Kings College Hospital in the early 1980s, at the epicenter of the AIDS epidemic, started his career in infectious disease, through the CDC, to Johns Hopkins. His pioneering work using data analytics to track the spread of STDs in Baltimore ended up in The Tipping Point, and served as the basis for significant studies of infectious disease and treatment.

In Episode 16 of Market Corner Conversations, Dr. Zenilman also discusses his thoughts about the disconnect between the country’s need for primary care physicians and the number of medical school graduates going into primary care. He thinks the misalignment of financial incentives between payers and providers, and between specialists and primary care, drives waste and poor health outcomes.

Dr. Jonathan M. Zenilman is a professor of medicine, dermatology and obstetrics and gynecology at the Johns Hopkins University School of Medicine, with joint appointments at the Johns Hopkins University Bloomberg School of Public Health. John is known internationally for his work in infectious disease epidemiology, especially regarding sexually transmitted infections at the CDC, Baltimore City Health Department. He’s a well-known researcher, author and mentor.
