Olfactory receptors play an important role in adaptation of a species to ecological niches. Insect olfactory receptors are different in two aspects from vertebrate and other invertebrate olfactory receptors which belong to the family of G protein coupled receptors (GPCRs). First, they form dimers composed of one odour-specific protein and one ubiquitous protein forming an ion channel. Second, compared with classical GPCRs the topology of the insect receptor proteins appears to be inverted. more>>>

The neural basis of olfaction is studied from a morphological and evolutionary perspective. We are examining the olfactory systems of Drosphilids, and small coeleopterans. Our key techniques are confocal microscopy, neural tracer and as well as electron microscopy (Cryo-FIB-SEM, SEM, TEM) to analyze the neural circuitry involved in olfaction in the arthropod brain. more>>>

My group investigates how odors affect the behavior of animals as different as vinegar flies, sphingid moths, desert ants, and hermit crabs. We try to understand the basic principles of olfaction either in an evolutionary approach, a neurophysiological approach and an ethological approach. more>>>

We investigate the impact of olfaction on different aspects in the life history of moths: finding valuable food sources, choosing a conspecific mating partner, and, in the case of female moths, deciding which plants are appropriate substrates to lay eggs. We are especially interested how ecologically important volatile compounds are coded in the antennal lobe, i.e. the first olfactory processing centre of the insect brain. more>>>
