Research

My research focuses on spatial & temporal scaling of hydrodynamical and biogeochemical processes – with emphasis on the interface between land and water bodies. My principal research objective is to improve the understanding of the linkage between surface water quality & the interplay of shallow groundwater flow pathways and chemical buffering within the near-stream zones. To achieve my research objectives, I combine field measurements with GIS-based landscape analysis and hydrological modeling.
