Willi Horner-Johnson is a Professor in the collaborative OHSU-Portland State University School of Public Health and in OHSU’s Institute on Development and Disability. She attended graduate school at the University of Illinois at Chicago, where she received a Ph.D. in Community Psychology with a minor in Statistics, Methods, and Measurement. Her research interests include disability-related disparities in health and access to care; pregnancy, contraceptive use, and other aspects of reproductive health of adolescents and adults with disabilities; and the potentially compounded disparities that may occur as disability intersects with other sociodemographic characteristics. Willi directs the Oregon Office on Disability and Health, is co-PI of the National Center for Disability and Pregnancy Research, and is leading an NIH-funded project on reproductive decision-making among women with developmental disabilities. Previously, she directed a multi-study project on health disparities at the intersection of race, ethnicity, and disability. She is a co-founder and former chair of the Disability Section of the Oregon Public Health Association, a past chair of the American Public Health Association’s Disability Section, and an editorial board member for Disability and Health Journal.
