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 Environmental Systems & Human Health Office OHSU – HRC3 314 Phone: (503) 346 – 3421

Dr. Needoba uses chemical and biological sensors deployed in the environment to characterize water quality and its determinants, with a focus on linkages between human activities, ecological processes, and human health. As part of the Ecosystem Monitoring Program supported by the Lower Columbia Estuary Partnership, the lab studies water quality and ecosystem characteristics of juvenile salmon habitat in the Columbia River estuary. Additional ongoing research addresses regional environmental health issues associated with harmful algal blooms, chemicals of emerging concern, and ocean acidification/hypoxia.

Associate Professor Epidemiology Office OHSU – HRC 11D32 Phone: (503) 494-4019

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.
