Research Program Summary

The overarching goal in my lab’s research is to assess how plant ecophysiological responses to environmental stressors affect plant performance or fitness. We use observational, experimental and modeling approaches to address key biological questions about ecophysiological, genetic, and evolutionary mechanisms that drive individuals and population level processes.  In the past I have addressed questions at scales ranging from biochemical to population and community level processes.  Within this framework, my research has evaluated (1) the roles that plant hybridization and evolution play in ecophysiological divergence of drought tolerance traits in sunflowers, (2) the genotypic and phenotypic responses of invasive plant populations to founding events, and (3) how the response of C3 photosynthesis to climate change alters plant productivity and fitness.

Current and Recent Research Projects

Student in the lab are currently investigating the ecophysiological and biochemical limits to photosynthesis of woody and herbaceous species in natural and managed ecosystems. We are also examining the tradeoff between carbon assimilation and hydraulics in forests. A related project is assessing the effect of global change on carbon dynamics in temperate deciduous forest. A central theme is to clearly understand the impacts of global change on plant productivity in natural and managed ecosystems to better predict plant and ecosystem responses to global change. An applied project seeks ways to improve carbon gain in crop plants. Applications to work in our lab are always welcome.
