I hold a degree in Engineering from the Federal University of Minas Gerais (UFMG, 1982) and a Ph.D. in Fundamental and Applied Toxicology, from the Paris Diderot University (Paris 7, 1989), granted by the Brazilian National Council for Scientific and Technological Development (CNPq) and French Committee for Engineer Studies (CEFI). I was a Professor of Environmental Biophysics at the Biophysics Institute of the Federal University of Rio de Janeiro (UFRJ). I also was a Programme Specialist in Ecological Sciences and the Man and the Biosphere Programme (MAB) at the UNESCO in Latin American and the Caribbean. I contributed to the development of the Ibero-American Network of Biosphere Reserves and the designation and implementation of Biosphere Reserves and Natural World Heritage Sites in the field, with particular focus on in marine and coastal areas. In Brazil, I worked as research fellow in the Rio de Janeiro Botanical Garden Research Institute, on marine ecology, biodiversity conservation and monitoring of coral reefs and rhodolith beds (calcareous algae) and macroalgae. Recently, I collaborated with a Sorbonne University project, in UN Decade of Ocean Science (2021-2030), to a Coastal Ocean Observatory for Climate Change, CO2 and Acidification in the global South. At the Botanical Garden Institute, I participate mainly in studies on the largest coralline reefs in South Atlantic, the Abrolhos Bank, and Doce River estuary on macroalgae and rhodolith beds.
