Research interests     

 

I study arthropods to better understand how human activity affects them and what this means for biodiversity conservation in the context of insect declines. My research combines ecological science with interdisciplinary and transdisciplinary approaches, exemplified by projects such as BioDivKultur. I also aim to promote the appreciation and protection of biodiversity within a social-ecological context, for instance, via science communication or applied approaches such as the Insect Calculator.
