Biography

Dr. Renato K. Braghiere is a Research Scientist at California Institute of Technology and NASA Jet Propulsion Laboratory, where he develops new generation Earth system models, which are required for more assertive climate projections in order to help scientists and policymakers to address issues related to climate change.

Dr. Braghiere research aims to better represent mechanistic processes of land surface models with the goals of: (i) understanding fundamental controls of land photosynthesis including the radiative transfer in vegetation canopies, as well as root uptake of water and nutrients; (ii) using state-of-the-art process-based models and remote sensing to refine local and global representations of the carbon and water cycles; and (iii) developing more informed projections of plant growth, especially under future climate scenarios.
