I worked in Kenya (Amboseli & Gilgil, 1981-84), Switzerland (University of Zürich, 1987-94), Germany (Max-Planck Institute, Seewiesen, 1990-98), Ivory Coast (Taï Monkey Project, 1988-2004), South-Africa (Loskop Dam Nature Reserve, 2006-2010) and France (Université de Strasbourg, 1998-2018) before retiring and returning to my native The Netherlands in 2018. I have been interested in the evolution of cooperation in all its forms throughout my career. Most of my empirical work was with free-ranging primates (baboons in Kenya; multiple forest species in Ivory Coast; vervet monkeys in South Africa). I was involved in some cooperation experiments with vervets (Strasbourg; South Africa) and with kea in captivity (Haidlhof, Austria). From my PhD onwards I have been busy developing a theory of ‘biological markets’ together with various colleagues, notably Peter Hammerstein.

Sabbatical at the NIAS (The Netherlands)
I spent the academic year 2011 - 2012 as a Lorentz Fellow-in-Residence at the Netherlands Institute for Advanced Study in the Humanities and Social Sciences (NIAS) in Wassenaar The Netherlands
Workshop in the Lorentz Center, Leiden (The Netherlands)
During my sabbatical I organized, together with Mark van Vugt (VU Amsterdam) a workshop "Cooperation in multi-partner settings: biological markets & social dilemmas" in the Lorentz Center in Leiden (16-20 January 2012).
Past international cooperations
Cooperation experiments with kea (Nestor nobilis), large parrots from New-Zealand held in aviaries at the Haidlhof, Austria. These experiments were conducted by students from Strasbourg under the supervision of Ludwig Huber, Gyula Gajdon and Raoul Schwing of the Messerli Research Institute, Veterinary Medical University Vienna, Austria

Economic Behaviour in Vervet Monkeys. A cooperation with E.E.C. van Damme of the Center for Economic Research of the University of Tilburg, The Netherlands financed by the programme 'Evolution and Behaviour' of the Netherlands Foundation for Scientific Research (NWO). Runs from 2003-2007
Taï Monkey Project. A research program that I founded in 1991 to study the behavioural ecology and several other topics in eight monkey species in the Taï National Park, Ivory Coast. The program is associated with the Centre Suisse de Recherches Scientifiques (CSRS) in Abidjan. In 2004 I left the program, but I still act as an adviser. A book on this project was published in 2007.
