The tree canopy is the first major compartment encountered by precipitation as it moves through forested ecosystems, and can dramatically transform the fate and transport of water and nutrient. My research seeks to understand the critical role of the forest canopy in determining net inputs with respect to forest type, meteorological conditions, and disturbance regimes. Much of my work is interdisciplinary, as I collaborate with entomologists, metagenomicists, ecologists, and environmental engineers, but the unifying question of my research aims to understand fundamental mechanisms controlling fluxes of water and nutrient. In order to enhance the predictive capability of ecosystem models (e.g., canopy interception, carbon, nitrogen), it is paramount to understand the physically-based processes that control these fluxes, which can only be achieved by intensive field observations. As such, my research quantifies watershed inputs and provides mechanistic answers that are key to understanding larger-scale watershed budgets in order to effectively manage forested ecosystems across multiple-use activities and services. My research, which is primarily field based, has been funded through the National Science Foundation and by private industry.
