Applied Epidemiology Group

Applied Epidemiology Group

The Applied Epidemiology Group (AEG) believes that public health is fundamentally a translational, applied science, which focuses on producing relevant and actionable work that will have immediate and long-term effects in affected populations. To this end, the AEG focuses on practice-based public health, including building, maintaining, and evaluating surveillance systems and data, conducting field, environmental, and outbreak investigations, and implementing public health programs and interventions.

The AEG is based on collaboration between the University of Nebraska Medical Center (UNMC) and the Nebraska Department of Health and Human Services (DHHS). UNMC and DHHS have entered an Academic Health Department (AHD) Partnership, which is designed to strengthen the links between public health practice and academia.  These AHDs “can serve as sites for joint education, research, and practice, enabling the practice and academic communities to work together to develop the current and future public health workforce, build the evidence base for public health, and better deliver the Essential Public Health Services.”
