Scientific projects

Bees and flowers evolved in a close relationship. In this interaction, flowers often provide cues such as odour and colour that bees use to find and recognize the flowers. I am highly interested in the communication process between flower-visiting insects and flowers. I investigate the behaviour-mediated volatiles involved in host finding by flower-specialist (oligolectic) bees.


Wild bees are among the most important pollinators of wild and cultivated plant species but suffer from ongoing land use intensification. The dynamics behind the ongoing wild bee declines are often hard to spot, as they are caused by multiple, interacting, and sometimes synergistic factors. As a scientific member of the BienABest project I am currently investigating the biodiversity of wild bees. The project aims to develop procedures to stop the drastic decline of wild bee populations and to protect and extend the ecosystem service "Pollination by Wild Bees".
