I am interested in the organization of collective behaviour in social insects, especially their mechanisms of self-organization. My model systems are leaf-cutting ants of the genus Atta and Acromyrmex.
Focal points of my research are:
- Nest building
- Organization of foraging
- Organization of division of labor
- Timing of social insect behaviour
