Cyrille is the co-founder of Organisation Ecotouristique du Lac Oguemoué (OELO), a non-profit research and conservation organization in central Gabon. He is investigating the impact of manatee hunting and the bushmeat trade in the Ogooué region of Gabon, investigating where illegal hunting and trade are taking place, and looking for ways to stop it. Cyrille also has a similar project focused on the slender-snouted crocodile, for which he received a Conservation Leadership Program Award in 2015. Cyrille and his organization also run an ecotourism site, Tsam Tsam.
