Education

Postdoctoral research in Life History Strategies and Evolutionary Ecology (2003-2005) at: The Norwegian University of Life Sciences, The Centre for Ecological and Evolutionary Synthesis at the University of Oslo, and Laboratoire de Biométrie et Biologie Évolutive at Université Claude Bernard Lyon 1 in France.
PhD in Ecology, Norwegian University of Life Sciences (2003)
MSc in Management of Natural Resources, Agricultural University of Norway
BSc in Wildlife and Forestry, University of Dschang, Cameroon


Research

My research interest is rather broad and includes natural resource management, population ecology, behavioral and evolutionary ecology, wildlife conservation and management, terrestrial ecosystems ecology and grazing ecology. During the last years, I have worked mainly with (1) the influence of environmental conditions (including global climatic change) on life history and population dynamics of ungulates, mainly large herbivores (e.g. reindeer/caribou, sheep); (2) life history strategies and evolutionary ecology of mammals, mainly reindeer/caribou and sheep, and (3) behavioral ecology (rutting behavior, mating strategies, social interactions, etc.). Together with colleagues from Norway and Finland, I am increasingly being interested in understanding sexual strategies (mating strategies, mate choice, costs of sexual reproduction, etc.) and the influence of the male composition (e.g. age structure, sex ratio) on population ecology of cervids. The major challenge of my research is to integrate all this knowledge so as to promote sustainable conservation and management of the biodiversity (fauna and flora). Indeed, I am also interested in (4) management and conservation of biodiversity in the tropics and plan to establish a long term research program in Africa. To achieve all these, I can count on collaborators in Canada, Norway, Finland, France, Uganda, South Africa and Cameroon, but also on the contribution from the students.
