I got a Bachelor degree in Geology, in Brazil, at the Pará State Federal University, an M.Sc. in Soil Science at Penn State University, and a 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 company that develops geospatial Apps for rural property management, monitoring and geotraceability of agroforestry products. In 2017, I have received the Conservation Fellowship from the Mulago Foundation for the work conducted in Terras. I am also engaged in crowdsourcing mapping and capacity building using Google Earth Engine, through the MapBiomas Project in Brazil, and contributing to forest monitoring in Brazil and Pan-Amazonia countries with the RAISG Network.
