BECS faculty also work with students enrolled in the Milken Institute School of Public Health to provide consulting services. Students in the Biostatistics MS and PhD programs, as well as those in the Epidemiology MS and PhD programs, are generally required to have supervised experience in biostatistical consultation on GW health-related research projects. The BECS Director and other faculty identify appropriate projects and provide supervision for this excellent learning experience.
