What to know
EIS is a competency-based training and experiential service fellowship in applied epidemiology. The EIS fellowship provides the opportunity for clinical and doctoral-level science professionals to learn in a structured two-year service and learning fellowship. By becoming a host site, your team will benefit from the service provided by an EIS officer with valuable clinical and scientific skills.
Being an EIS Host Site

During the two-year fellowship, host sites are responsible for providing supervision, mentorship, and day-to-day experiential training in applied epidemiology. The EIS program provides multiple structured trainings for the officers and guidance and operational support for supervisors. The supervision and mentorship you provide as a host site prepares the officers to be applied epidemiologists and public health leaders, fosters long-term partnerships, and ultimately shapes the public health workforce.
EIS officers benefit from training and support provided by the EIS program and host sites. Benefits to host sites include:
- Valuable clinical and scientific skills of EIS officer at minimal or no financial cost to the site
- Opportunities to participate in the EIS program's trainings for supervisors
- Opportunity to cultivate future public health leaders with a mutual appreciation for and skills needed to successfully navigate complex challenges of interagency networks/collaborations
