I did my undergraduate degree in Geology, in Brazil, at the Pará State Federal University, a M.Sc. in Soil Science at Penn State University, and Ph.D. in Geography at University of California in Santa Barbara. I am a senior researcher at Imazon and conduct research on spatial analysis and on remote sensing for mapping and monitoring forest changes. In 2010, I received the Skoll Award on Social Entrepreneurship in recognition to the development and operationalization of SAD - the first independent forest monitoring system in Brazil. I had also co-founded Terras App Solutions a startup firm that develops geospatial Apps for rural property management, monitoring and geotraceability of agroforestry products. I am currently engaged in crowdsourcing mapping and capacity building using Google Earth Engine, MapBiomas Project in Brazil, and contributing with forest monitoring in Brazil and Pan-Amazonia countries.
