Research Summary

I am a plant and ecosystem ecologist, focusing on plant-nutrient-soil interactions in high latitude ecosystems. I am interested in how plants respond to climate-induced environmental change in arctic ecosystems, and the interactions between plants, microorganisms and nutrient cycling. My research focuses on the patterns of plant nutrient uptake, carbon and nitrogen cycling, and resource partitioning in relation to newly released nutrients from deep-soil permafrost thaw and surface-soil decomposition. Across multiple dimensions, I explore the linkages between plant-plant and plant-microbe competition for nutrients, plant species composition, belowground ecosystem processes, and ecosystem-atmosphere dynamics – vertically within the soil profile, laterally across the landscape, and temporally through seasonal and multi-year studies. My work is fieldwork-based, where I use a combination of methods, including field manipulation experiments and in situ stable isotope labeling in order to follow the ecological processes directly as they occur in the arctic environment.
