The Society for Epidemiologic Research (SER) was established in 1968 as a forum for sharing the latest in epidemiologic research. The SER is committed to keeping epidemiologists at the vanguard of scientific developments. To this end, the Society sponsors the American Journal of Epidemiology and Epidemiologic Reviews, as well as the annual SER meeting which includes the John C. Cassel Memorial Lecture and contributed papers, symposia, and posters on a wide range of epidemiologic issues.
