My research aims to understand the hydrological and biogeochemical processes controlling the mobilization, transformation, and transport of solutes from land to surface waters. My empirical work focusses on processes operating at hillslope, riparian (near-stream), and catchment scales with the ambition to upscale that understanding to the larger landscape scale. I am especially interested in the role of the riparian zone versus the upland area in controlling surface water quality. During my PhD, I developed the idea of a dominant source layer (DSL) within the riparian zone, a conceptual model that explains timing and amount of solute transfer from soils to surface waters. In addition to my conceptual modelling, my research interest and expertise includes biogeochemical and hydrological modelling. I am familiar with the INCA family of models for solute dynamics at the catchment scale, and with the rainfall-runoff models PERSiST and HBV.
My interests expand to the quantification of anthropogenic related impacts on catchment biogeochemistry, including climate change and land use management. Ultimately, my goal is to improve our fundamental understanding of soil to stream solute transport processes that can support successful management strategies for aquatic resources, specifically surface water quality.
