My research broadly focuses on multi-scale influences of disturbance (drought, permafrost thaw, warming, elevated CO2on the relationship between ecosystem structure (above- and belowground plant community and traits, landscape setting and microtopograhy) and function (CO2 and CH4 fluxes, carbon sequestration, organic matter decomposition, etc) . Examples of previous projects include the effect of drought on carbon (C) fluxes in continental Canadian fens and the effect of permafrost thaw on structural drivers of C fluxes in the discontinuous permafrost zone. I am also interested in regional and global-scale drivers and dynamics of carbon sequestration.

At ORNL, I am studying the effect of ecosystem warming and elevated CO2 on fine-root traits and their link to peatland C function at SPRUCE (Spruce and Peatland Responses Under Climatic and Environmental change). I am also investigating the link between root phenology and soil respiration, and their relationship to moisture limitation in an oak-hickory forest (MOFLUX).
