Catherine O'Reilly's research focuses on lakes and streams, studying water quality, nutrient cycles and biogeochemistry, with an interest in impacts of land use and climate change.
Lakes are affected by climate in a variety of ways. Lake Tanganyika, East Africa, has declines in productivity and fish yields.
Agricultural land use can lead to degraded water quality. We study patterns in nutrient losses and how practices improve water quality.
Urban land use characteristics and sewersheds can influence water qualtiy in urban streams.
