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

I'm broadly interested in understanding how trees interact with their environment, how forests respond to climate change and management activities, and how science can be used to help conserve forest ecosystems into the future. My current research is focused on examining coast redwood and giant sequoia tree responses to environmental change, particularly drought. I'm also involved in projects aimed at conserving biodiversity in an ancient Malaysian dipterocarp rainforest, understanding how management activities can help to improve forest resilience to climate change, comparing water use strategies of coast redwood, coast live oak, southwestern white pine, and quaking aspen trees in California and Arizona, and monitoring microclimates in diverse ecosystems at UC Natural Reserves throughout California. My research utilizes diverse methods and tools from the fields of plant physiology, forest ecology, stable isotope biogeochemistry, remote sensing, and micrometeorology. 

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 Physiological Ecology 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 love exploring wild places and enjoy tree and rock climbing, mountaineering, backpacking, surfing, skiing, biking, and sharing the beauty of the world through photography and videos.
