Scientific projects

Bees are one of the most important groups of pollinators in the globe. Wild bees are responsible for reproduction of wild plant species but also of plants consumed by humans through pollination. Despite the pivotal role of wild bees in the stability of ecosystem services, recent reports on bee population dynamics agree that wild bees are being threatened with reduction of its diversity/abundance especially in agricultural environments. I am a behavioral ecologist with a background in the natural history of wild bees, bee-plant interactions and molecular ecology. My research is based on experimental biology at the laboratory and at (semi) field levels. Currently I am coordinating a project “Wild bee reproduction”. The aim of the project is to enhance our overall knowledge over the role of organic farming practices in wild bee conservation. Moreover, I perform experiments to assess potential causes of bee decline on agricultural fields by studying the effect of environmental stressors on behavioral dynamics and its consequence in the reproduction of wild bees.

Lastly, I am part of the coordinating group of the project BRASILICO, in Brazil. In this collaborative study, we are performing a simultaneous and systematical monitoring of wild bees at a common plant species (basil).
