Our laboratory examines the effects of anthropogenic activities on freshwater ecosystems. We quantify the movement of inorganic and organic contaminants from urban and agricultural activities as it is degraded and/or exported downstream. Additionally, we quantify the effects of these contaminants on aquatic organisms across trophic levels and evaluate the role of microbial dynamics in contaminant transport.
Specific Goal: Develop predictive models of contaminant abundance and effects on aquatic organisms to aid management of freshwater ecosystems.
In our research, we:
- Quantify transport metrics of inorganic and organic compounds
- Measure potential for microbial degradation of compounds under variable physicochemical characteristics
- Assess toxicity of contaminants on aquatic organisms using non-lethal endpoints such as growth and fecundity
