I am a behavioural biologist who is interested is social cognition and socio-ecology of primates. I work as lecturer at the Animal Behaviour & Cognition group, where I am involved in teaching in the Biology bachelor programme and Environmental Biology master programme. Besides my role as lecturer, I am currently working on my PhD-research at Leiden University/Apenheul Primate Park. During my PhD, I study the cognitive processes underlying mate preferences of zoo-housed orang-utans, and I try to identify methods to measure these preferences. To do so, I run behavioural experiments with both zoo-housedn orang-utans and humans.
