Research interests

I am mainly interested in tropical ecosystems ecology, carbon dynamics and nutrient cycling, remote sensing of land use change and disturbances (Fires) and the interactions between human, climate and forest functioning.

I have worked in Amazonia over 8 years being evolved in several projects including the evaluation of the impacts of fire events in Roraima-Brazil in 1998, the LBA Project: Amazonia‘s Large Scale Atmosphere-Biosphere Experiment, since 2000, I recently joined the RAINFOR – Amazon Forest Inventory Network - project, been involved in four major projects:

  1. PAN-AMAZONIA – Project for the Advancement of Networked Science in Amazonia, between 2004 and 2006
  2. Examining the impacts of recent drought in Amazonia in 2006
  3. Why do different Amazonian forests grow at different rates?
  4. Mapping and quantifying post-fire carbon budget in Amazonia

My major contribution has been to show how the high landscape variability, including land cover, land use and topography affect the spatial patterns of the canopy structure and functioning. More recently, I have shown the effects of soil fertility in the patterns of carbon allocation in forest ecosystems across the Amazon. Finally, I have generated the first basin-wide map of the 2005 Amazonian drought and showed how it impacted fire patterns in this region.
