I study the interaction between terrestrial plants and the global climate system. I am particularly interested in how plants respond to environmental conditions and how these responses affect projections of global environmental change moving forward. Some of the questions we are trying to answer include:
- How do plants acclimate to long-term changes in environmental conditions, including temperature, atmospheric carbon dioxide concentration, and drought?
- How much carbon dioxide will plants take up from the atmosphere in the future and how does this affect climate projections?
- How do human land management decisions, particularly within agricultural systems, influence future climate projections?
My lab uses a combination of plant physiological and ecological studies alongside computer simulations to answer these questions. For more information, visit www.smithecophyslab.com.
