Welcome to the Vanni Lab. We study the ecology of lakes and their watersheds. We are interested in how lakes are affected by what happens in their watersheds, in particular changes in agriculture. Another area of interest is the role of animals in mediating biogeochemical cycles and ecosystem processes. We employ many research approaches, including long-term studies, field and lab experiments, and modeling.
