Julann A. Spromberg, Ph.D.

Background

Julann is a toxicologist who studies chemical impacts across levels of biological organization. She joined the Ecotoxicology Program at NWFSC in 2002 as a National Research Council Post-Doctoral Associate to investigate how toxicity-induced biological responses may translate to population-level impacts on endangered species. She is interested in integrating toxicology with ecological factors to find feasible ways of protecting biodiversity from chemical and anthropogenic impacts. Julann received a B.S. in Environmental Science from Huxley College of Environmental Studies at Western Washington University and a Ph.D. in Toxicology from the Graduate Center for Toxicology at the University of Kentucky.

Current Research

Julann's research focuses on linking contaminant exposures to population-level effects in animal populations. This is done by integrating information on ecology, toxicology, physiology and life history into computer models to assess risk to threatened and endangered populations. Her work has focused on direct and indirect toxic impacts due to environmental contaminants (including metals, pesticides, PAHs, and stormwater) on Pacific salmon and other endangered fish populations.  She assists in investigating impacts of urban stormwater runoff, and particularly on the causes and consequences of pre-spawn mortality of coho salmon in urban streams.  She also provides science support for Biological Opinions and other projects promoting NOAA's mission.
