I am a marine biologist and conservationist, developing research on sea turtle spatial ecology and migration. Committed to marine and environmental conservation since 2002, I have been developing and managing research and conservation programs, focusing on sea turtles and marine and coastal ecosystems in Oman, Brazil, Angola, Cape Verde, Guinea Bissau and São Tomé and Príncipe, in several remarkable international organisations. Through these years of working experiences, I have been developing scientific research initiatives towards conservation and a comprehensive community-based marine conservation program that integrates research, ecological monitoring and protection of critical sites, but also close societal impact by developing environmental education and conservation awareness.

Research interests

I am interested in improving our knowledge of the sea turtle populations nesting and foraging in Sao Tome Island, in the Gulf of Guinea, West Central Africa. My research centres on understanding spatial and temporal movements, foraging grounds, reproductive ecology, and the impacts of anthropogenic threats. Multiple methods, such as site-based monitoring, mark-recapture, telemetry, genetics and stable isotopes and an evaluation of environmental factors and anthropogenic threats will be used during this research. These methods when effectively combined will guide science-based conservation, management priorities and strategies, and define key protected areas.
