Changes in temperature and precipitation extremes are resulting in severe or prologned droughts, and warm droughts are predicted to become more common. These events are already contributing to increased mortality of forests, greater pressure on water resources, and stressing food production.

Our group seeks mechanistic understanding of ecosystem responses to climate dynamics that underly these important issues facing society by looking at plant ecophysiology coupled to hydrology, and specifically by looking through the lens of plant hydraulics. In our research we combine observations, development of biophysical models, data analytics such as Bayesian methods, and genomics.
