Joseph A. Needoba, Ph.D.

  • Associate Professor, OHSU-PSU School of Public Health


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.
