Current Research

Our work focuses on the factors regulating productivity and nutrient cycling in terrestrial ecosystems. Research in my lab tends to focus on biogeochemistry and global change in forest ecosystems although we have recently expanded into peatland research in northern MN. Our work is a combination of field studies and experiments, data synthesis from the literature and numerical and simulation modeling. At present we have a significant focus on plant C allocation, plant-microbe interactions, and belowground element cycling. The research spans micron-to-global scales. As such, our perspective is generally integrative, focusing on how the different components of an ecosystem (soils, microbes, plant species) interact with the physical environment to affect biogeochemical cycling.

Our work in global change stems from the fact that human activity is transforming the basic function of the terrestrial biosphere at an accelerating rate. Fossil fuel combustion is increasing the concentration of carbon dioxide in the atmosphere. Fixation of atmospheric N by humans now exceeds the rate of non-anthropogenic N fixation. Changes in land use and the introduction of invasive species have legacy effects on carbon storage and biogeochemical cycling that last decades. While the broad-scale patterns of ecosystem and planetary change are well understood, there remains as much uncertainty in model representation of underlying processes as there is in the behavior of humans over the next decades to centuries. Through our research we hope to reduce the uncertainty in models by providing high-level data constraints for model development.

Graduate students in my lab work on many different types of research projects. I encourage incoming students to tackle questions of interest to them and to have overlapping interests with my area of research expertise. If you are interested in graduate work with me, please contact me, I am more than happy to describe ongoing research projects and possibilities in my lab. Thank you.
