Currently I am an Associate Professor of the Faculty of Sciences of University of Lisbon, leading the Ecology of Environmental Change research group of cE3c (Centre for Ecology and Environmental Changes). My research focuses on understanding ecological patterns at the ecosystem level in response to environmental changes. For many years, I have been involved in studying the impact of anthropogenic activity in the structure and functioning of ecosystems. My current research is driven by three overarching objectives: i) Understand the structure and functioning of dryland ecosystems (including agro-ecosystems and agroforestry ecosystems) under environmental change scenarios (eutrophication, climate change and pollution); ii) Develop, test, model and track early warning ecological indicators of environmental change factors at global scale, as well as, ecotechnological solutions for restoring ecosystem structure and functioning; iii) Understand what is the role of urban green areas and of its biodiversity in ecosystem functioning and ecosystem services;
