My research work mainly focus on developing and establishing a robust multiscale parametrization scheme for water and solute transport modeling at a regional to continental scales. Current work include development and applications of multiscale Hydrologic Model (mHM), water Quality Model (mQM), innovative methods for providing reliable predictions of hydroclimatic extremes (floods, droughts, heatwaves), prediction in ungauged basins (PUB) uncertainty and risk assessment for integrated water resources management, data-analytics and statistical approaches for analyzing coupled water-food-energy nexus, hydrological assessments under changing environmental and climate condtions.
