Jason T. Magnuson, PhD
Dr. Jason Magnuson is a Research Biologist at the Columbia Environmental Research Center.
Dr. Magnuson researches the influence of environmental contaminants and abiotic stressors on fish health. He uses molecular-level endpoints, such as transcriptomics and metabolomics, to link to higher levels of biological organization, including histopathology, physiology, and behavior, to understand the toxicity of aquatic pollutants to fish. Previous research projects have involved the relationship between mercury and selenium molar ratios to fish stress responses, the impact of pesticides to neuroendocrine, olfactory, swimming performance, and neurotoxic responses to salmonids, the effects of polycyclic aromatic hydrocarbons present in crude oil on early life stage eye development and fish visual function, as well as the toxic response of contaminants when present as a mixture or co-exposed with ultraviolet radiation and temperature. Additionally, current research projects have focused on the impact of pharmaceuticals on early life stage fish development.
