My research investigates how human activities alter water, and ultimately how this influences the health and biogeochemistry of natural ecosystems (nutrient cycling, productivity, gas exchange). Given the swift turnover and transformation of many chemical contaminants in water, strict measurements on these quantities by themselves can yield an incomplete (or possibly misleading) picture of environmental quality. Microbes often dominate material transfer in natural ecosystems (e.g., productivity, decomposition) and respond swiftly to environmental conditions, making them early-warning indicators of system change. As such, these biochemical links serve as analogues for more complex biochemical systems that are often difficult to study.

Specific areas of research interest include:

• Ecology of freshwater protists
• Role of phytoplankton and microzooplankton in aquatic food webs
• Nutrient limitation in aquatic in streams and lakes
• Causes and consequences of hypoxia in large lakes
• Developing biogeochemical metrics to set nutrient load limits for aquatic ecosystems
