Areas of interest: forest ecology and biogeochemistry
In general, I am interested in 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. My research is primarily field based using observational and experimental approaches. I am particularly interested in how interspecific differences in resource uptake and loss affect the distribution of carbon and nitrogen in terrestrial ecosystems. I am also interested in the interaction between microbial activity and forest dynamics. Thus my 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.
My interest 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.
Graduate students in my lab work on many different research projects. I encourage incoming students to tackle questions that are of interest to them whether they be related to my current projects or otherwise. 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.
