Research Statement


My research centers around the intersection of ecosystems and climate change. In particular, I strive to understand the future of Earth's forests in a changing climate. Massive mortality events of many tree species in the last decade prompt concerns that drought, insects, and wildfire may devastate forests in the coming decades. I study how drought and climate change affect forest ecosystems, including tree physiology, species interactions, carbon cycling, and biosphere-atmosphere feedbacks. This research spans a broad array of spatial scales from xylem cells to ecosystems and seeks to gain a better mechanistic understanding of how climate change will affect forests around the world.
