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.

Alan Teo is a core investigator at the Center to Improve Veteran Involvement in Care at the VA Portland Health Care System, and an assistant professor with dual appointments in School of Public Health and the Department of Psychiatry at OHSU.

He was drawn to a career in health care while an undergraduate at Stanford University studying how human health is influenced by complex interactions between biology and culture.

His research focuses on the role of social relationships in influencing mental health outcomes. In partnership with colleagues in Japan, he promoted a new field of research on hikikomori, a severe form of social withdrawal. His and his colleagues’ research demonstrated its presence all over the world, and helped to underline the importance of public awareness and early intervention for social isolation. He also has led efforts demonstrating the potent effects of positive social connections in preventing major depressive disorder.
