Viviana Zalles Post-Doctoral Associate vzalles@umd.edu Viviana has a bachelor's degree in Environmental Science and has earned her PhD in Geographical Sciences at the University of Maryland. She is interested in using remote sensing to research large scale land cover change and its drivers, particularly in the context of tropical deforestation.
