Biography

Earth's ecosystems are in a state of unprecedented change. My focus is on building better tools to monitor and understand these ecosystems, in particular how they exchange carbon with the atmosphere. My doctoral research developed a new approach to mapping photosynthesis across the globe using satellite measurements and models. My current research uses state-of-the-art instruments and models to better understand how terrestrial ecosystems respond to environmental change.
