My research focuses on the reactive nitrogen cycle, with an emphasis on nitrate deposition. My interest in reactive nitrogen (e.g., NOx) extends from its connection to air quality through its impact on ozone and hydroxyl concentrations to the biogeochemical cycling of nitrogen in the earth system via formation of nitric acid (or nitrate), a major component of acid rain and a source of biologically available nitrogen.

I have explored several topics throughout my career from water controls on carbon and nitrogen dynamics in arid and semi-arid ecosystems to the consequences of changes in biodiversity on the functioning of ecosystems, including the development of biodiversity scenarios for the next 50 years. I am particularly interested in working with scenarios as a way of simplifying, understanding, and communicating the complex relationships that emerge from the study of social-ecological systems.

My lab is interested in the adaptive evolution of developmental, physiological, and life history traits in natural plant populations. We use quantitative genetics, QTL mapping, and association studies of candidate loci to examine the genetic basis of natural variation in ecologically important traits in Arabidopsis thaliana. We also measure natural selection on these traits and the loci underlying them in the field by experimentally manipulating environments, phenotypes, and genotypes.
