I’m broadly interested in understanding interactions between trees and their environment, and how drought and climate change affects forest ecosystems. To address these questions, I use methods and tools from the fields of plant physiology, forest ecology, stable isotope biogeochemistry, micrometeorology, and remote sensing. My current research is focused on examining the effects of climate change on coast redwood (Sequoia sempervirens) and giant sequoia (Sequoiadendron giganteum) trees in California as part of the Redwoods and Climate Change Initiative and through a collaborative project with scientists from Sequoia and Kings Canyon National Parks, U.S. Geological Survey, and Carnegie Airborne Observatory at Stanford.
Effects of tree height on branch hydraulics, leaf structure, and gas exchange in California’s redwood species

It is commonly assumed that transpiration does not occur at night because leaf stomata are closed in the dark. We tested this assumption across a diversity of ecosystems and woody plant species by various methods to explore the circumstances when this assumption is false. Our primary goals were: (1) to evaluate the nature and magnitude of nighttime...
