In addition to its collaborative role in research and the cross-campus training it provides to the basic, clinical and population sciences, the Department of Epidemiology & Biostatistics formally provides specific services in biostatistical and bioinfomatics consultations (Pletcher/McCulloch) through the Clinical and Translational Sciences Institute (CTSI) as well as support for complex, large-scale, high-volume research through its Data Systems Services (DSS) group.
