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.

Professor Epidemiology, Health Promotion, & Community Health Office OHSU Central Oregon – Community HUB Phone: (541) 728-0665
Biography

Jackilen Shannon is a nutritional epidemiologist who works to understand the distribution and determinants of disease at the population level. Much of her early research focused on translating scientific findings to the medical clinic. In recent years, she has shifted some time toward working to translate medical research to the population at large through community engagement.

At OHSU, she co-developed and expanded an education and research program called “Let’s Get Healthy!” that provides personalized health education to school children and adults. She has also helped build that program internationally, helping to create Let’s Get Healthy!-Global as part of OHSU’s partnership with Bangkok Dusit Medical Services and Mahidol University in Thailand.

Snowden, Jonathan - PhD

Assistant Professor Epidemiology Office OHSU – CSB 652 Phone: (503) 494 – 0904
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.
