As a landscape limnologist, the focus of my research is to gain a better understanding of lakes and their place in the landscape. Lakes can be studied at three important spatial scales: within-lake, lake catchment, and the landscape, and my research includes all three. My main lines of research are: (1) The effects of land use on lake nutrients and biological communities; (2) Development of a landscape-context paradigm for lake ecosystems; (3) The application of a landscape-context paradigm to lake assessment and management; and (4) Quantifying ecosystem reference conditions.
