Research Theme: I have long been interested in how carbon and water relations change in trees as they grow larger and older, and also in the impacts of exotic forest plantations on ecohydrological processes. My current research focuses on the impacts of complex, mountainous terrain on ecosystem processes, and much of my work involves developing methods to measure and monitor ecophysiological and ecohydological processes in complex terrain. Current research topics include 1) the use of nocturnal air drainage and the isotopes of respired CO2 in the drainage flow as an indicator of ecosystem metabolic processes; 2) relationships between vegetation water use and streamflow in small basins; and 3) development of new sensor-network technology to facilitate long term, continuous measurements in complex ecosystems.
