Research Interests


Terrestrial ecosystem and carbon cycle modeling

Earth Science: Ecosystem function

My research focuses on the modeling of terrestrial ecosystems, biogeochemical cycles, and their responses to climate change. I use mathematical modeling, simulation of ecosystem processes, and game theory to understand plant demographic and eco-physiological processes and their effects on ecosystem structure, carbon, nutrient, and water cycles across various scales. I also use data assimilation approaches to improve model parameterization and analyze model structure and uncertainty.
