Louise's research focuses on the ecological effects of anthropogenic stressors, specifically environmental toxicants. Her work combines theoretical and empirical approaches to understand the effects of a toxicant on individual organisms, identify environmental and ecological feedbacks that impact toxicity, and ultimately extrapolate effects observed at the suborganismal or individual-level to the population-level. Her main focus is on freshwater systems and is interested in an array of compounds such as nanomaterials, PCBs, heavy metals and pesticides. Louise has developed dynamic quantitative models to both help design experiments and explain empirical results. The ultimate goal of her research is to accurately predict population-level effects of a stressor using suborganismal and individual-level data.
