Ecosystem ecology, tropical forests, global change, remote sensing, plant ecophysiology

I am a broadly trained ecosystem ecologist, driven to understand the fate of forests in the face of global change. Over the last decade, my work has focused on tropical forests particularly in the Brazilian Amazon. The forests of the Amazon basin constitute the world’s largest intact tropical rainforest and are critical to global climate function and biodiversity, as well as providing many other ecosystem services. But the future of these forests, and the carbon and they contain, is highly uncertain. My work aims to resolve key uncertainties associated with the responses of tropical forest structure and function to climate and land-use change. I use a variety of approaches, from remote sensing to field observations, within the context of large, international collaborations.
