Research Theme: Human activity has caused extensive changes in inputs of various nutrient and toxic elements to many ecosystems. My lab studies the changes in biogeochemical cycling, and the effects on the vegetative community, that has arisen from human activities. Most of my current research is focused in the H.J. Andrews Experimental Forest. We have established plots to examine the effects of changing detrital quality on C balance, and nutrient cycling and availability.
