Personal information

Born in 1969 in The Netherlands, I grew up with a naturalist father, who taught me at an early age the birds in our neighbourhood. From 1988-1993 I studied Biology at the universities of Wageningen, Groningen and Oxford, focusing on avian reproductive ecology. I finished my PhD at the Netherlands Institute of Ecology in 1998 on density dependence and individual optimisation of avian reproductive rates. Since then I have worked as post-doctoral researcher at the universities of Bangor (UK), Groningen, California (Santa Cruz) and again at the Netherlands Institute of Ecology. Since 2004 I joined the Animal Ecology Group of Groningen University again, and in 2007 I obtained a personal research fellowship from the Dutch research council (NWO).
