Ericka is an aquatic ecologist with approximately 15 years of experience working on a diverse set of research projects that span project management of endangered amphibian recovery and disease ecology, native freshwater mussel habitat modeling, anadromous fish food web structure assessment, and stormwater mitigation decision science. She also has experience with space use modeling for desert tortoises, wildfire risk modeling, and vulnerability mapping. She has extensive experience collecting biological, habitat, and water quality data in both urban and wilderness settings. Her technical skills include database development and management, GIS spatial analysis and cartography, and R coding and statistical analysis.
