My research focuses on understanding how aquatic ecosystems are responding to regional to global change and the consequences of these changes for the people who rely on them for the ecosystem services they provide. Though my work is mostly done in lakes, I have also conducted research in coastal-estuarine systems and even small headwater streams. Because temperature influences the basic functioning of lake ecosystems in a variety of ways, much of my work seeks to understand the consequences of warming surface temperatures for lake ecosystem properties. For example, warming of surface waters results in declines in deep-water oxygen in lakes. My current project is exploring how this deoxygenation will affect the bioaccumulation of toxic mercury in fishes sought by anglers.
