My work lies at the intersection of fundamental and applied research. I draw on ecology and evolution – as well as the humanities and social sciences – to develop solutions for protecting crops that respect both humans and non-humans. Ethical and effective innovation relies on original research and solutions that are both technical and systemic.

Fruit flies, particularly Drosophila suzukii and Drosophila melanogaster, are my primary research subjects. Through my work with them, I explore, in particular, the relationships between hosts and symbionts (i.e. microbiota) and reproductive biology. These organisms allow for highly realistic ecological conditions (microcosms, wild strains, etc.) in order to shed light on how natural systems function.
