Our Faculty

More than 150 faculty members work within the OHSU-PSU School of Public Health. They have a wide range of expertise, from monitoring and assessing health risks and opportunities in populations, to helping build health-supporting social environments through policy, advocacy, and programs. They are educators, advisors, researchers, practitioners and community leaders. They come from backgrounds in quantitative, behavioral, environmental and social sciences, policy and government, exercise and health sciences and anthropology, among many other areas. They all work in collaboration with each other and with community partners, and are especially focused on the training and education of future leaders and practitioners in the public health fields.

Associate Professor Epidemiology Office OHSU – CDRC 1272C Phone: (503) 494-9273
Biography

Willi Horner-Johnson is an associate professor in the School of Public Health and in OHSU’s Institute on Development and Disability. She studies health and health care disparities impacting adults with disabilities and has contributed to a growing body of evidence indicating substandard receipt of some types of preventive care and elevated levels of unmet health care needs in the disability population.

Horner-Johnson has a particular interest in disparities experienced by people with disabilities who also belong to other marginalized groups. In 2014, she guest edited a special issue of Medical Care on health care disparities at the intersection of disability, race and ethnicity.

Much of her current research focuses on reproductive health of women with disabilities, including contraception use and preferences and pregnancy occurrence and outcomes.

Horner-Johnson co-founded the Disability Section of the Oregon Public Health Association and is currently chair of the Disability Section of the American Public Health Association.

Biography

Carrie Nielson is an epidemiologist focused on genetic risk factors for osteoporosis and other outcomes of aging that are related to body composition and endocrinology. She and her colleagues work to understand the regulation of bone, fat, and lean mass in older adults in order to prevent frailty and fracture, which lead to immobility and loss of independence. She works primarily on two large cohort studies of aging men and women in the United States, using genotyping in these cohorts to explore genetic variants that may affect bone mineral density and other traits.

Assistant Professor Epidemiology Office OHSU – CSB 658 Phone: (503) 494-0300
Biography

Seth O’Neal is an assistant professor of epidemiology in the School of Public Health. He also holds a visiting faculty position at Universidad Peruana Cayetano Heredia in Lima, Peru, and is co-director of the university’s Center for Global Health in Tumbes, Peru.

O’Neal is engaged in research to develop cost-effective and sustainable control interventions for neglected tropical infections in resource-limited settings. His primary focus is on Taenia solium, the pork tapeworm, which is an important cause of preventable epilepsy across much of Latin America, Asia and sub-Saharan Africa. The parasite also perpetuates poverty in these regions by inflicting financial losses on small landowners due to contaminated pork. Through National Institutes of Health and foundation funding, O’Neal conducts community trials of control interventions, as well as clinical and epidemiological studies. His research explores the biological, environmental, social and cultural factors that drive transmission of the parasite, as these affect control interventions.

Biography

Jonathan Snowden is an epidemiologist, an assistant professor in the School of Public Health and in OHSU’s Department of Obstetrics & Gynecology. He also is an associate editor for the national Patient-Centered Outcomes Research Institute.

Snowden’s research focuses on sexual and reproductive health disparities. He evaluates methods and concepts to improve causal inference from observational data, and his trans-disciplinary research sits at the intersection of population health science, clinical practice and health care policy.

Snowden aims to frame research questions that are relevant to the affected populations and that  respect the circumstances of people’s lives, so that research results can promote optimal health in the real world. By more clearly defining variations in the continuum of “normal” healthy sexuality and reproduction, his research aims to preserve optimal health as well as prevent and treat disease.

A cross-cutting focus of his research is the clear communication of novel concepts and methodologies.
