Conservation science | Primatology
I manage an in-situ conservation project (Projet Grands Singes/ PGS ) in East region, Cameroon, which aims to enable coexistence of wild great apes and local people in a community living in the northern buffer zone of the Dja Biosphere Reserve – an exceptional priority area for great ape conservation. PGS Cameroon seeks external funding and strategic partnerships for development initiatives in the villages, and collaborates closely with local authorities to increase awareness and application of wildlife law in the region. PGS Cameroon facilitates the conservation-applied research programme of the Centre for Research and Conservation (CRC) of Antwerp ZOO and Planckendael ZOO, which aims to understand the drivers of biodiversity loss and the mechanisms of balancing the needs of nature with those of people living within the Dja Landscape. PGS Cameroon maintains a research camp (La Belgique) in Dja buffer zone, where the CRC, associated researchers and students can implement their work.
I am copyeditor for the Journal of Zoo and Aquarium Research (JZAR)
I am a conservation scientist with a particular interest in the drivers of change in tropical ecosystems. My overarching goal is to monitor the drivers of biodiversity loss and to understand the mechanisms of coexistence of people and nature. I use a multi-disciplinary approach, combining ecology, biology, social science, tropical and climate science, etc., and increasingly consider a broad landscape/ecosystem perspective. I have a particular interest in the socio-ecology, behaviour and survival of chimpanzees and gorillas and I study the effect of human activities on great ape abundance, in particular hunting, logging operations and researcher presence and activity: the majority of such research has clear conservation applications.
I obtained a Bachelor’s degree in Zoology at the University of Wales, Cardiff, UK, in 2000, and then defended my PhD in Evolutionary Ecology at Southampton University, UK, in 2004. I have since lived and worked in Central Africa, predominantly involved with great ape conservation and research projects. In particular, I volunteered in the Republic of Congo for 1 year, and then worked for Max Planck (EVAN), Leipzig, in Loango National Park, Gabon for 2 years, on the launch of a chimpanzee and gorilla habituation and research project. Since then I have worked for the Centre for Research and Conservation (CRC) of Antwerp ZOO and Planckendael ZOO: in Cameroon for 4 years – during which time I re-launched PGS from temporary closure and helped re-build the project’s infrastructure – and later back in Europe, being based in Antwerp and now UK. Since returning to Europe, I concentrate on disseminating the scientific output and conservation impact of PGS, seeking external funding, building research collaborations and strategic partnerships, supervising PhD and Masters students and developing the PGS project and research plan.
