Research and Practice Interests
My research in my early career centered on developing fish, invertebrate, and plant bioasssessment and ecotoxicology methods to assess the biological integrity of lakes, streams, rivers, and estuaries. My current research activities are to bring genomic tools to bioassessments and ecotoxicity tests to assess ecosystem health and develop water quality criteria and water quality standards and limits that can be used in regulatory programs of emerging contaminants (i.e., EDCs and pharmaceuticals) and ion toxicity. l also have worked on invasive toxic Algae like Golden Algae P. parvum. They are invading inland reservoirs due to increases in salinity.In addition, I am currently working on microplastic, PFAS-free Foam Flame Retardants, and cyanotoxins. I have also developed short-term chronic toxicity methods for Daphnia magna, the fatmuck mussel Lampsilis siliquoidea, the parthenogenic and the parthenogenic mayfly Neocloeon triangulifer. Currently developing a short-term chronic method for rainbow trout Oncorhynchus mykiss and brook trout Salvelinus fontinalis.
