Willi Horner-Johnson, PhD

Willi Horner-Johnson conducts research to evaluate community-based health promotion interventions for people with disabilities and community engagement efforts to increase access to health care for people with disabilities at the local level. She is experienced in analyzing population-based data, particularly around surveillance of disability prevalence, health risks among adults and youth with disabilities and special health needs, and quality of life. She is also part of a national team working to develop a measure of health that does not penalize based on functional limitations (i.e., people with disabilities are not automatically assumed to be unhealthy).
