I received my M.Sc. on Ecology and Environment at the Animal Biology Department from the Faculty of Sciences Antananarivo, based upon a habitat used of collared brown lemur (Eulemur collaris) in Madagascar’s littoral southeastern forest.  I carry out lemur’s fieldwork to develop their distribution and census data in Madagascar. I’ve also published lemur surveys in different regions of the island such as western dry forest, Central high plateau and eastern evergreen humid forest. I’m member of IUCN Primate Specialist Group and scientific member of GERP association (Scientists group for primate’s studies in Madagascar). I’m a faunal expert and project manager within Biotope Madagascar.
