The School's culture reflects its commitment to interdisciplinary approaches to challenging public health issues. The School's divisional structure also reflects the multi-dimensional nature of the field by its core disciplines: Biostatistics, Environmental Health Sciences, Epidemiology and Community Health (comprised of core faculty in biological epidemiology and social and behavioral sciences) and Health Policy and Management. Today the School successfully incorporates and integrates the three goals of the University mission, and cherishes excellence in each. Moreover, its organization in core disciplines reflects its obligation as a nationally accredited school to deliver professional and academic education in each of these fields as the minimum expected of a school of public health. The School, of course, far exceeded these minimums in each area as it grew and expanded through the 1990s. While each discipline embodies a primary focus, the complexity of public health issues propels natural collaborations across the divisions and partnerships with other collegiate units. That said, the School is continually re-evaluating its internal structure with a view to increased effectiveness and efficiency.
