Research
My field is global ecology, and my research emphasizes ecological contributions across the range of Earth science disciplines. My colleagues and I develop diverse approaches to quantifying large-scale ecosystem processes, using satellites, atmospheric data, models, and census data, and explore global-scale patterns of vegetation-climate feedbacks, carbon cycle dynamics, primary production, forest management, and fire. At the ecosystem-scale, we conduct experiments on grassland responses to global change, which integrate approaches from molecular biology to remote sensing.
Teaching
I am one of five professors who teach the Earth Systems field studies course for advanced undergrads and co-terms at Jasper Ridge Biological Preserve. I also teach an introductory seminar on climate change for freshmen.
