Profile

I am a Natural Environment Research Council (NERC) Research Fellow at the Environmental Change Institute. My main research focus is to examine the remote sensing of tropical forest disturbances: such as deforestation, drought and fires, and on-the-ground quantification of carbon stocks and fluxes in tropical forests, specifically in Amazonia, to understand the impacts of human pressures and climate change in this ecosystem. Read more about my NERC fellowship research.

I was granted a 3-year Research Fellowship by NERC in 2008 to study the carbon cycling of fire-affected forests in Amazonia, bridging remote sensing analysis and field-based surveys in Amazonia. I formerly completed my PhD degree from Brazilian Institute of Space Research in 2004 and since completing my PhD, I have been working as a Posdoctoral Research Associated at the Environmental Change Institute.

My research has include a number of fieldwork campaigns in tropical forests, integration of field-based ecological data, satellite remote-sensing and ecological modelling for the understanding of spatial and temporal patterns of carbon dynamics and nutrient cycling in Amazonia and Atlantic forests, from local to regional scales.

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 three 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?

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 been trying to understand the effects of soil fertility in the patterns of carbon allocation in forest ecosystems across the Amazon.

Research Interests

I am mainly interested in tropical ecosystems ecology, carbon dynamics and nutrient cycling, application of remote sensing for up-scaling ecological variables and understand how land cover and landscape heterogeneity affects forest functioning.

Dissemination of results

I have a keen interest in the wider dissemination and discussion of my research through presentations at seminars and conferences and interaction with the media. I have made key oral presentations at a number of recent conferences and workshops, including the Panamazonia Workshop (Caxiuana, Brazil, 2004, invited speaker), the International Workshop for Canopy Research PELD/GCP (Brazil, 2005, invited speaker), the LBA-Forest Disturbance Synthesis Workshop (New Orleans, USA, 2006, invited speaker and Salvador, Brazil, 2007), Climate Change and the Fate of the Amazon Conference (Oxford, UK, 2007, invited speaker), among others. My work was also quoted in several articles for the general public including BBC News (Amazon "faces more deadly droughts", March 2007). Planet Earth ("Amazon: the beginning of the end?", NERC, pages 12-13, Spring 2007), Blueprint Newsletter ("Will climate change kill the Amazon", , University of Oxford, v. 7, n.9, April 2007). FAPESP Agency ("Caminho livre para o fogo", April 2007, Brazil), Pesquisa FAPESP journal ("The stressed forest: researchers evaluate the effects of the 2005 Amazon drough", April 2007, pp 48-49, Brazil).
