He was a researcher at CONICET, Argentina, and a professor at the University of Mar del Plata. His research focus is on the human and social dimensions of environmental change, with emphasis on how stakeholders make decisions that make an impact on the environment. His main study area is the South American Gran Chaco, where he had been practicing inter- and transdisciplinary research to reconcile agricultural production and biocultural conservation. He was the lead author of the regional and global assessments on biodiversity and ecosystem services undertaken by IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services). His interactions with local stakeholders, regional governments and inter-governmental platforms have spurred his interest in the science-policy interface, where he is actively learning and participating.
