Research Interests
Dr. Hanson is an aquatic ecotoxicologist and ecological risk assessor who focuses on fate and effects of pesticides, wastewater contaminants (e.g., nutrients, pharmaceuticals, microplastics), and unconventional oil. The impacts of these contaminants on non-target species and the ways in which these can influence responses (direct and indirect) observed at the population, community, and ecosystem-level are studied at the laboratory to field-level. The use of mesocosms, model freshwater ecosystems, along with developing new toxicity bioassays in a rapid and effective manner are a core feature of his research program. Dr. Hanson and his team also develop methods to critically evaluate data quality and reporting in the peer reviewed literature for inclusion in risk assessment, including weight of evidence approaches to assign causality.
