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.

Yves Labissiere is a social psychologist who works to understand how race, identity, language, difference, power and privilege play a role in education and health systems. His aim is to develop strategies that heal and empower individuals and transform systems.

He has studied the health effects of gentrification and residential displacement on black men in Portland, and has worked on curriculum for Portland State University’s EXITO program, which works to build infrastructure to support underrepresented students interested in the health sciences. He works on a project with the Portland Police Bureau to test how positive police-community interactions might help address crime and build trust. He is also working on a new project with Portland police to better understand how police work with, or could better work with, mental health professionals when they encounter calls that involve people who may need mental health help.

Robert A. Lowe is a professor in the School of Public Health, the OHSU Department of Medical Informatics and Clinical Epidemiology and the OHSU Department of Emergency Medicine. He is also the founder of the OHSU Center for Policy and Research in Emergency Medicine.

Lowe has performed extensive health services and epidemiologic research. His major research focus is access to care for vulnerable populations, with a particular focus on the role of emergency departments  in access to care and on the relationship between access to primary care and use of emergency departments. For example, he has studied enrollees in a Medicaid managed care organization, examining the associations between characteristics of their primary care providers and the enrollees’ rates of emergency department use. He demonstrated a large rise in emergency department use by uninsured Oregonians after cutbacks in the Oregon Health Plan.
