My research addresses the interactions of physical, ecological, and human systems, with water resources serving as a common nexus. My work typically involves developing environmental monitoring programs that facilitate understanding catchment processes, as they vary both naturally and anthropogenically over different spatial and temporal scales. One current research focus area is determining if intensive agrarian systems on sloping lands in SE Asia are environmentally sustainable in terms of water availability, water quality, land degradation processes (e.g., erosion, landslides), biodiversity, and carbon sequestration. In particular, how does the environmental footprint of intensified systems, such as permanent cultivation, greenhouse agriculture, and monoculture plantations of rubber and oil palm, compare with that of traditional swidden practices? Other emerging focus areas are (1) determining the extent of co-facilitation among of mangroves, seagrass, and coral ecosystems; (2) modelling environmental processes with artificial intelligencemodels; and (3) examining the linkage between hydrological processes, infectious disease, and human health in developing countries.
