Hari Ram Upadhayay

Hari Ram is a catchment system scientist interested in determining the sources of sediment and associated diffuse pollutants using state-of-the-art stable isotopes (bulk and compound-specific) and Bayesian mixing modelling.  More broadly, he is interested in human-induced land use changes and wildfire impacts on the sources, transport pathways and turnover rates of organic carbon, diffuse pollution budgets and overall landscape degradation. He has extensive knowledge of the biogeochemistry of specific vegetation markers (e.g. long-chain fatty acids) in soil and aquatic systems and a broad understanding of several catchment processes relevant for managing agriculture diffuse pollution. He is a member of Professor Adie Collins' team and is currently working on combining isotopic, optical and geochemical properties of organic carbon and fine-grained sediment for understanding the spatial and temporal mismatch between on-farm management and landscape scale responses in the context of policy targets.
