I have developed hyper-resolution global hydrological models, which can provide locally relevant but globally available information. My primary focus is on how dam construction and its operation have changed and will change water resources and hydrology, specifically surface water storage and extent dynamics. The primary domains of interest are the Contiguous US and the Mekong river basin, which is shared by six Southeast Asian countries, where the unprecedented boom in hydropower dam construction has been occurring. Now at UMD, I am working for developing a Dashboard for Agricultural Water use and Nutrient management (DAWN).
