Please see Erika Ziller’s publications on Digital Commons.
Erika began her career as a social worker in rural Maine where she quickly realized that many of the challenges facing her clients were exacerbated by health and social policies that were unresponsive to their needs. Since then, she has been committed to policy-informed research aimed at reducing health disparities for vulnerable populations, particularly rural residents. In her 20 years with the Maine Rural Health Research Center, Erika has directed numerous studies on rural health care access, coverage, and health reform, including several analyses of the importance of public health insurance (Medicaid and CHIP) in ensuring coverage for rural residents. In 2011, Erika received the Louis Gorin Award for Outstanding Achievement in Rural Health Care from the National Rural Health Association in recognition of her contributions to rural health policy. Erika grew up in small-town Maine and obtained her PhD in public policy from the University of Southern Maine in 2012.
