My research projects are within the scientific domains of behavioral ecology, sociobiology and evolution of social insects. Besides my experimental-analytical work I am interested in developing new conceptions and syntheses which are in part reflected in some of my books. In particular my research focusses on questions in communication biology and chemical ecology.
Current research projects are:
- Mechanisms and evolution of the regulation of reproduction and division of labor in ant societies.
- Multimodal signals in ant communication.
- Territorial strategies and home range orientation in ants.
