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.

Assistant Professor Health Studies, Applied Health & Fitness, Health Promotion, Community Health Office PSU – URBN 450F Phone: (503) 725-5121

Brad Wipfli’s research concentrates on health promotion and health behavior change. He is interested in identifying effective behavioral and environmental change strategies that impact physical and mental health. He also investigates the ways in which changes in health behaviors impact physiological processes and clinical indicators of illness and disease.

Wipfli won the 2009 Dissertation of the Year award from the National Association of Sport and Physical Education for his work discovering that post-exercise improvements in depressive symptoms are mediated by reductions in serum serotonin. He has also been a part of several pioneering Total Worker Health interventions, including the groundbreaking Safety and Health Involvement for Truckers study, which is the largest health and safety intervention with truck drivers in U.S. history. He is currently leading an intervention aimed at improving health, safety, and well-being of workers in sedentary occupations (see here).
