I am a physiological plant ecologist who uses experimental and observational approaches to understand how plants respond to natural stresses and environmental pollutants. My research focuses on below ground activities, root biology, water relations, gas exchange and nutrient cycling. There are three major components in my current research, all of which focus largely on physiological mechanisms that control plant response to global climate change. These are: 1) plant and ecosystem responses to elevated levels of atmospheric CO2 concentration; 2) plant and ecosystem responses to increased atmospheric nitrogen deposition, and; 3) importance of extreme events (episodic drought and extreme heat) as an agent of natural selection in plant communities. These subject areas are closely linked as they cover the core components of environmental issues related to global warming and climate change.
