We study various questions in the context of chemical ecology, covering several research fields, such as behavioural ecology, evolutionary ecology, invasive biology, host-parasite interactions, natural history and community ecology. Our study models are ants, the most specious and diverse group of social insects. Ants interact in manifold ways with other organisms, including higher animals, plants, fungi and micro-organisms. Those interactions range from parasitic to mutualistic and we study them from proximate and ultimate perspectives. Proximately, interactions are frequently mediated by semiochemicals. Pheromones play mayor roles in the regulation of insect societies, in recognition processes and in collective information transfer. We attempt to understand the very basic mechanisms in the communication of ants for building theoretical models and simulations of collective behaviour. Furthermore, we analyse differences among ant species in their communication, with a specific focus on invasive species, in order to understand ultimately why some species can become dominant over other species.
Chemical interactions play also major roles in interspecific interaction and such mechanisms are also studied in our group. Numerous animals exploit ant societies in parasitic ways by means of chemical deception, such as mimicry. Ultimately, we focus also on co-evolutionary dynamics in host-parasite systems by quantifying reciprocal selection pressures.
I am furthermore interested in understanding fundamental mechanisms of ant communication with respect to human applications in business and social life. Social insects are prime examples for swarm intelligence. Their self-organized interactions result in collective achievements which are far beyond individual abilities. This is of special interest for business bionics, not only in the context of social media. I exchange and share my insights with representatives from economy in seminars and workshops (European Communication Summit Brussels 2012, Fachtagung Interne Kommunikation Berlin 2012, Querdenker Bionik-Tag München 2011, and others)
