RESEARCH INTERESTS

My research focuses on the need to minimize disturbance of the local and regional energy, carbon and water balances in Mountain Pine Beetle attacked forest stands with the goal to provide experimental data required in modeling carbon dioxide (CO₂), water vapour (H₂O) and sensible heat transfer between MPB-attacked forest ecosystems and the atmosphere. Specifically, I analyze the impact of management strategies on stand microclimate, growth conditions and exchange processes. These detailed assessments are essential to understand the dynamics of insect-disturbed ecosystems and to improve the current soil-vegetation-atmosphere transfer (SVAT) schemes used in regional-scale carbon and climate modeling.

In particular my goals are (1) to quantify and compare the changes in microclimate and growth conditions (radiation, temperature and wind regimes) in the canopy of lodgepole pine stands following different management strategies, (2) to identify the vertical distribution of sources, sinks and the nature of exchange processes of sensible heat, H₂O and CO₂ in those forest stands, and ultimately (3) to contribute to an enhanced and more accurate implementation of canopy-atmosphere interactions in SVAT schemes.
