My research focuses on the neuroethology of social insects, in particular mechanisms underlying communication, orientation and behavioral plasticity and their consequences for social organization. Main aspects of my research are the function and evolution of olfactory systems and neuronal mechanisms of behavioral plasticity associated with polyethism and division of labor. Projects employ modern experimental techniques in functional and molecular neuroanatomy (confocal 3D imaging, immunolabeling and – blotting), neurophysiology (in-situ electrophysiology and calcium imaging), as well as quantitative behavioral assays (choice behavior, learning and memory, environmental influences). The integrative perspective on the behavior of social insects represented at the department of Behavioral Physiology & Sociobiology combines neurobiology, behavioral ecology, sociobiology and evolutionary biology.
Current research projects are:
- Function, organization and evolution of olfactory systems
- Developmental and adult plasticity of olfactory and visual brain centers and social organization
- Structural and functional plasticity of neuronal microcircuits in memory centers
- Neuronal basis of orientation and navigation
