My research is concerned with the development and application of quantitative techniques for studying the dynamic behavior of large-scale aquatic and terrestrial systems. Methods of time series analysis, statistical inference and hypothesis testing, Monte Carlo simulation, and recursive parameter estimation are used in conjunction with empirical and mathematical models to identify and quantify the important processes operating within ecosystems. An important aspect of this approach is an evaluation of uncertainties arising from the spatial heterogeneity and the different temporal and spatial scales inherent in large natural systems.

Along with my students, I apply these techniques to questions of environmental change, with an emphasis on the response of hydrochemical systems to changes in land use and to changes in atmospheric and climatic inputs. Most recently, my research has focused on the effects of acidic deposition on the biogeochemical cycles of catchments in North America and northern Europe. These efforts include field studies and modeling of the interactions among soil, water, and biota in manipulated catchments and in intensively monitored lakes and streams. In addition, I am involved with research associates in the U.S., Great Britain and Scandinavia in the design, implementation and analysis of regional surveys of surface waters for the purposes of resource assessment and policy formulation.
