Dr. Litvak studies ecohydrological processes in cities to identify environmental, biological and social factors that shape urban environments, and uses this knowledge to develop sustainable solutions for cities with diverse climatic and hydrologic conditions. Her work is fundamentally interdisciplinary, involving collaboration with hydrologic modelers, remote sensing experts, and social scientists. Dr. Litvak’s research is based on in situ measurements of urban evapotranspiration and the physiological responses of urban plants to their environments, which are key to understanding relationships between plant water use, landscape composition, environmental conditions, and management practices.
