From 2019 to 2021 she was a member of the Mission Assembly for Adaptation to Climate Change, including Societal Transformation (Horizon Europe 2030 - EU). Among different roles in scientific and directory boards of anthropological associations, she was the President of the Portuguese Association of Anthropology (2006-2009) She did fieldwork in rural Portugal, and among indigenous peoples in Brazil and Timor-Leste. Her main topics include identity, personhood, kinship and place, land ownership, and indigenous transformation. In Portugal she carried out fieldwork in a rural village in centre Portugal (1992-1995), dealing with identity, ageing and personhood. From 2004 to 2005 she acted as scientific coordinator of research on gender in rural areas in central and northern Portugal, on the use of common lands and women contribution to organic food gardens. In 1997 she started fieldwork in Brazil with participant observation (total of 12 months, plus 4 months in scattered periods) on the study of Amerindian Peoples of Lowland South America - in particular, the mixed-blood Tupinambá de Olivença who inhabit in southern Bahia. Her contribution to this area has been the integration of Amazonian ethnological debates with the ethnography of the indigenous peoples of the Atlantic Forest. Starting from 2003, she was the Principal Investigator of a interdiciplinary research team and consultant for FUNAI in the process of recognition by the Brazilian Federal State of the Indigenous Territory of the Tupinambá of Olivença, being asked by the Tupinambá themselves to act as coordinator and author of the respective Anthropological Report (Relatório Circunstanciado de Identificação e Demarcação da Terra Indígena Tupinambá de Olivença). In Timor-Leste she did fieldwork in Lautém totaling 8 months among the Fataluku speaking people on place and historicities of belonging, kinship, ancestorship. This is mostly addressed etnographically, through the relationship of the Fataluku to tombs and burial sites of becoming ancestors and martyrs. She is currently setting up a research program aiming at developing perspectives on land belonging in circumstances resulting from the new climate regime. This involves PhD students and colleagues in Brazil. The research focuses on historicities of entanglements with the land sustained, on the one hand, in resistances to monoculture projects and, on the other, on revitalization of ruined landscapes by monoculture of eucalyptus. The first perspective involves research in Lautem/Timor Leste and in the Atlantic forest/Brazil, as well as in Mato Grosso do Sul. and develops indigenous anthropogenic long-term contribute to biodiverse forest. The second is sustained in research in rural central Portugal and among indigenous people in the Atlantic forest in Brazil who are dealing with the revitalization of ruined landscapes by monoculture of eucalyptus. She has published a monograph on the Tupinambá in Brazil (Silent Land, 2007) co-edited with Rui Graça Feijó the book Transformations in Timor Leste (ed. Routledge 2017) and has been publishing her work extensively in international scientific journals and edited books.
