Recent and Current Research:

• Influence of tree height and stand structure on canopy water flux
• Coupling water and carbon fluxes in complex landscapes
• Nutritional imbalance as a predisposing factor in Swiss needle cast disease: An explanation of increased vulnerability of Douglas-fir stands to this normally endemic disease
• The effect of wild fire/prescribed fires on nitrogen dynamics within riparian and stream ecosystems
• Use of nitrogen isotopes to determine contribution of marine-derived nutrients to inland riparian forests
