|I am a physiological ecologist who focuses on understanding the evolution of functional traits in plants and the impacts of climate change on ecosystems. I investigate physiological or plant-mediated processes from the spatial scale of cells to that of whole landscapes. A recent focus of my scholarship is understanding the dynamics of climate-ecosystem interactions and their influence in coupling of carbon and water cycles in arid landscapes, which encompass ~ 40% of Earth’s surface. I am interested in the plant processes underlying these coupling and how these patterns and mechanism are related to processes in diverse biomes from around the globe.|
