I am most interested in research at the intersection of environmental chemistry and toxicology. My educational background has led me here with degrees and research experiences in biology, environmental science, toxicology, and environmental chemistry. My students and I use both laboratory and field work in our research; the laboratory studies let us answer specific questions in a controlled setting, while the field work is where the application of that work occurs. The majority of our work has focused on the impacts of aquatic chemistry on metal toxicity in aquatic environments. We have also done work on PAHs in groundwater and black liquor in pulp and paper mill effluent. Collaborations have included scientists from the government, private, and university sectors. I recently (Sept. 2011) returned from Eawag in Switzerland where I investigated the impacts of NOM on Ag Nanoparticle chemistry and algal toxicity.
