My research program spans multiple levels of biological organization and modes of inquiry to advance the science and practice of conserving freshwater ecosystems. My principal interests include ecohydrology (dams, environmental flows), community ecology (freshwater fishes, amphibians, invertebrates), invasion biology (science and development of management tools), macroecology (testing and advancing the field of biogeography), climate change (impacts and adaptation strategies), and conservation biology (science and implementation at local and regional scales). Although my research program focuses on these major areas, my enthusiasm for research bridges both basic and applied ecology. A common thread throughout this research is a strong emphasis on the application of quantitative approaches to data analysis, including the development of innovative statistical techniques for exploring complex ecological data.
