My research program is focused on two problems: (1) quantifying how populations and ecosystems are responding to variation in the environment across large spatial gradients, and (2) reducing or eliminating biological sources of uncertainty in the global carbon cycle. I focus on the development and application of remote sensing technologies that allow us to explore questions at scales of space, time and biological organization that are beyond the grasp of existing tools to examine. My work has been externally supported by NASA, the NSF, DOD and USDA, and I am a funded co-Investigator and member of the Science Team of the NASA Global Ecosystem Dynamics Investigation (GEDI) mission.
