My current research focuses on the intersection between forests, soils, and climate to understand how trees are physiologically responding to climate change and how different tree species will adapt to future climates. I use a variety of stable isotope approaches to identify the seasonal water sources that trees have access to, and how trees regulate water loss and carbon assimilation in response to increased temperatures and water deficits. Overall, my research program aims to better understand and predict the vulnerability of different forest communities to stress and mortality under the warmer, drier conditions that arise with climate change, and how exposure to these conditions varies across different forested landscapes as a function of topography and underlying hydrologic processes.
