Research Interests

My collaborative team based out of Burlington, VT studies changes in tree health and productivity associated with abiotic stress (e.g., acid deposition, changing temperature and precipitation, reduced snowpack, ice storms, etc.). This is accomplished by evaluating trends in native populations and trees in manipulated experiments at Hubbard Brook (e.g., watersheds 1 versus 6, NuPert, snow removal plots, the ISE experiment, etc.).
