Community Engagement

My community engagement takes a couple of forms. First, I am not in academia full time. As the Director of Public Health Systems and Planning at the Association of State and Territorial Health Officials, I spend most of my time directly supporting leaders and staff in governmental public health. I’m engaged in numerous committees and initiatives through this work including the Public Health Performance Improvement Network, the Public Health Improvement Training, in support of the Public Health Accreditation Board, and in providing direct technical assistance to states, territories, and freely-associated states. Additionally, I serve as a Medical Reserve Corps volunteer in Vermont and, in 2021, was the Vaccination Branch Director for 90 days as part of Vermont’s response to COVID-19. Finally, I mentor and provide career planning support to both Vassar College and Yale School of Public Health students interested in the field.
