I am fascinated by how trees withstand environmental stress over centuries, or even millennia. In Canada’s forests, the stresses of low nutrient availability and winter cold are common, yet trees survive and thrive across much of our landscape. I study how trees take up and allocate nutrients, particularly nitrogen, often with the help of mycorrhizal partners; and how they alter their physiology to tolerate freezing temperatures. I am particularly interested in co-adaptation of conifers and their mycorrhizal partners, and in variation among tree populations in stress tolerance.

My work ranges from lab experiments using ion-selective microelectrodes to measure net flux of nutrient ions in mycorrhizal roots, to field work assessing nutrient stoichiometry of foliage, fungi and soil.
