Sagar Gautam is an environmental scientist motivated to work on identifying the environmental impacts of land use and climate change on soil, water and air. He develops and implements the models (process model and machine learning models) to quantify the impact of human induced change on different environmental fluxes. The overall goal of his research is to use the environmental flux observation datasets and different genera of models to predict the fate of environmental fluxes (flow, water quality, soil carbon etc.) under changing climate and land use, benchmark and improve process representation in models to reduce uncertainty in prediction.
