Research Interest
My research interests are focused on three areas: 1) to understand if plants use resources efficiently and to use optimization principles to scale leaf-level photosynthesis at the ecosystem level; 2) quantify and model different components of the carbon cycle in tropical terrestrial ecosystems; 3) to relate the functional features of the plants with images obtained with remote sensors to estimate different ecosystem services.
