Research Interests

My research examines the impact of various emerging contaminants (e.g. nanomaterials, pharmaceuticals) as well as natural stressors on freshwater organisms. We are using genomic data as a tool to investigate the impacts of these various potential stressors and to develop biomarkers of exposure and effect to be used as tools for ecological risk assessment. The goal of my research is to inform the sustainable development and use of chemicals.
