I'm a canopy biologist currently working as a research scientist with three organizations: the Department of Integrative Biology at UC Berkeley, the Institute for Biodiversity Science and Sustainability at the California Academy of Sciences, and the UC Institute for the Study of Ecological and Evolutionary Climate Impacts.

I'm interested in understanding how trees and forests are affected by environmental change, how tree and forest structure influence canopy biodiversity, and how this information can be used to help manage and conserve forests in a rapidly changing world. My current research is focused on examining how coast redwood and giant sequoia trees in California respond to climate change, particularly drought. I'm also involved in research projects aimed at understanding and conserving plant diversity in the ancient dipterocarp rainforests of Malaysia, and examining water use strategies of coast redwood, Pacific madrone, southwestern white pine, and quaking aspen trees in California and Arizona. My research utilizes diverse methods and tools from the fields of plant physiology, forest ecology, stable isotope biogeochemistry, and micrometeorology. 

I am grateful to have the opportunity to work in amazing places and collaborate with many incredible mentors and colleagues.

I received a B.S. in Natural Resources Planning from Humboldt State University (1992), a M.S. in Forestry from Humboldt State University (2004), and a Ph.D. in Tree Ecophysiology from UC Berkeley (2009). In addition to my academic career, I have worked in various positions as a forestry and GIS technician, forest firefighter, environmental advocate, and U.S. Peace Corps volunteer in the Kingdom of Tonga, South Pacific. 

I enjoy tree and rock climbing, mountaineering, backpacking, surfing, skiing, biking, exploring, and sharing the beauty of the world through videos and photography.
