Global Change Biogeochemistry

Plant productivity,  ecophysiology, and phenology in a warming Arctic

I was a research assistant on the Ecotypes Project based at Toolik Field Station in the North Slope of Alaska. We studied the plasticity and response of Arctic cottongrass to warming and changing seasonality with in-situ warming chambers and a reciprocal transplant experiment. I also set up an experiment to look at plant responses to soil drying from precipitation change and permafrost thawing.

Air pollution, nitrogen deposition, and urban forest functioning

As lab manager at research technician in the Templer Lab at Boston University, I worked on the Urban New England Project, examining the combined effects of forest fragmentation and urbanization on forest function and biogeochemistry across the landscape of Northeast US secondary forests. We also studied interactions between urbanization, air quality, and ecosystem processes, including at continental scale with data collection and longitudinal analysis of the National Atmospheric Deposition Program network.

Biogeochemical silica and carbon cycling across the land-to-sea continuum

As an undergraduate, I conducted research with the Porder Lab at Brown University, the Tang, and Melillo Labs at the Marine Biological Laboratory in Woods Hole, and the Carey Lab at Babson College. We examined the effects of soil warming on the fluxes of silica through plants, soils, and watersheds, to understand how climate interactions with geochemical weathering and biological cycling would drive the availability of this nutrient to terrestrial and marine ecosystems. We further explored how climactic change in the Arctic would affect the coupled cycling and export of silicon and carbon.
