Personal profile


After studying biology at the University of Groningen I did my PhD under supervision of Joost Tinbergen at the department of Animal Ecology of the Netherlands Institute of Ecology (NIOO - KNAW) - and in 1995 defended my PhD thesis "Reproductive decisions in great tits; An optimality approach" (Cum laude). After Postdoc positions at the University of Bristol ( John McNamara , Mathematics Department), Oxford ( Chris Perrins , Dept. of Zoology) and University of Uppsala ( Lars Gustafsson , Dept. of Zoology) I obtained an 'open competition' NWO-grant, enabling a return to the University of Groningen. In 2004 I was awarded a Vici-grant, enabling the creation of a new research group (animals@work) embedded in the Behavioural Biology group, and we are continuing the work started with that project.
