I am an aquatic ecologist interested in both basic and applied aspects of water quality, with strong emphases on processes contributing to water quality impairment and on sustainable management of aquatic ecosystems. Generally, I study how abiotic and biotic processes in lakes respond to multiple stressors, including anthropogenic activities and climate change, which often operate at different scales. In particular, I am interested in predicting how interactive pressures of large-scale landscape modification and climate change will alter aquatic ecosystem structure and functioning, as well as provisioning of ecosystem services. To elucidate these water quality patterns and processes and identify underlying mechanisms, my research incorporates regional field studies, statistical analyses of large empirical datasets, and data-driven approaches. My research considers some of the most important environmental issues facing society (e.g., cultural eutrophication, biodiversity loss, novel cyanobacteria toxins) and longstanding ecological theories (e.g., biodiversity-ecosystem functioning, ecosystem stability, trophic dynamics), and integrates concepts from diverse disciplines (e.g., ecology, natural resources management, engineering, social sciences).
