Our group collaborates with colleagues within and external to Johns Hopkins on a variety of projects.


John W. Ayers
John W. Ayers is an epidemiologist whose work is at the intersection of Internet technologies and, chronic disease and health promotion research. He harnesses an array of digital databases, including Internet search queries, news media, social media, and online networks (e.g., Facebook) that he mines using advanced statistical methods and social science theory. Beginning in 2011, he led the first effort to apply such data to non-infectious diseases by forecasting the popularity of electronic cigarettes, a prediction that has been actualized in the time since.
