Angelo has over two decades of dedicated service in biodiversity conservation within Madagascar’s unique ecosystems. Since 1999, he has contributed significantly to the field through his work in Protected Areas across the island, beginning while preparing his Master’s degree at the University of Antananarivo.

Specializing in the conservation of Critically Endangered species, Angelo is known for his expertise in conservation genetics and population management of the Ploughshare tortoise. During his tenure at Baly Bay National Park from 2005 to 2011, he worked closely with local communities on reintroduction programs and population surveys using distance sampling methodology. His research revealed population declines driven by poaching and fire, leading him to establish community patrol systems and coordinate mixed brigade operations that resulted in multiple poacher arrests.

Angelo is skilled in Geographic Information System (GIS) and SMART (Spatial Monitoring and Reporting Tool) technology, integrating NASA FIRMS fire alerts and Global Forest Watch deforestation data into patrol planning. Since 2017, he has served as the implementation lead for SMART community patrol systems across six Protected Areas in Madagascar, including Menabe Antimena, Ankarafantsika, Baly Bay, Alaotra, Lake Sofia, and Ambondrobe. His research on Ploughshare tortoise population monitoring and conservation genetics has been published in peer-reviewed journals that have garnered international attention from the conservation community.
