I am a climate scientist, and I study interactions between plants and the atmosphere. I am especially interested in understanding how plants respond to increasing CO2 and climate change, and how those plant responses influence the Earth system by altering land energy and water fluxes. Climate models are the primary tool for much of my research - I run model experiments to learn about the mechanisms through which plants interact with the atmosphere, and I analyze climate model simulations from the Coupled Model Intercomparison Project (CMIP) to explore the drivers of uncertainty across models. I also analyze ecological and atmospheric data at multiple spatial scales, from site-level observations to global-scale remote sensing products.
