Role of the hydrologic cycle in the natural climate system at regional sclaes; impact of climate change on hydrology, ecosystems, and agriculture; and the role of hydrology in shaping transmission of vector-borne diseases (e.g malaria and dengue fever). New theoretical models are developed and tested against satellite observations and archived data sets of hydrologic and atmospheric variables, as well as observations collected in field campaigns. These models are then used to reproduce observed natural phenomena, or to predict the impact of human activity on climate, hydrology, and/or disease transmission.
