My research lies at the intersection of remote sensing with hydrology, hydrometeorology, and geomorphology. My work involves the application of state-of-art remote sensing observations in combination with numerical and statistical models to advance understanding and predictability of water cycle components and weather-related hazards at a range of spatial and temporal scales.
