We all greatly depend on the ecosystem services provided by freshwater resources, and yet human impacts on aquatic ecosystems continue to be critical. Moreover, because these impacts range from local to global, direct to indirect, and short-term to long-term, aquatic ecosystem research is a challenging but important task. I am interested in the ecological effects of exotic species, ultraviolet radiation, temperature, and other stressors on freshwater ecosystems. Some of my current projects include the ecology of the exotic water flea Daphnia lumholtzi, the effects of leaf litter leachates on zooplankton life history, and the interactive effects of UV and pesticides on zooplankton. Please visit my website for the details of these and other projects, especially if you are a student interested in joining my lab! Recently, I have also delved into a new area of research that has interested me for a number of years: public awareness and perceptions of environmental issues such as climate change. I am working with Dr. Sojung Kim at George Mason University on several projects that examine public awareness and concern of ocean acidification.
