Dr. Murphy joined the Maine Cooperative Fish and Wildlife Research Unit in 2020 as an Assistant Unit Leader - Fisheries. She holds a graduate faculty appointment as an Assistant Professor in the Department of Wildlife, Fisheries, and Conservation Biology in the College of Natural Sciences, Forestry, and Agriculture at the University of Maine.

Teaching Interest

Fish ecology and conservation (2019, Oregon State University)

Research Interest

Dr. Murphy's academic interests are centered on top down and bottom up responses to disturbance, especially hydrological alteration. This includes evaluations of nutrient, light and habitat availability, phytoplankton, zooplankton, benthic insects, fish pathogens, and diverse fish assemblages.
