With a background in Geography (Federal University of Rio Grande do Sul, Porto Alegre, RS, Brazil) and a M.S. and Ph.D. in Remote Sensing (Brazilian Space Agency/National Institute for Space Research, Sao Jose dos Campos, SP, Brazil), my research is centered within the area of biosphere-atmosphere interactions. The overall question that has motivated my research is: how do biophysical properties of plants and ecosystems influence the regional climate due to the exchanges of energy, water and carbon between the surface and the atmosphere? More specifically, my research focuses on how land use and land cover changes and different regimes of disturbance (i.e., fire, droughts) affect the ecophysiological processes and, consequently, the partitioning of surface fluxes. Addressing these questions is essential for an improved understanding of the survival and fitness of plants, plant species distribution, and for the prediction of ecosystem responses to future climate change.
