My main interest are mutualistic and parasitic protists from insects with a special focus on flagellates from lower termites and spore-forming protists fom cockroaches and beetles. Using light, transmission and scanning electron microscopy I study the biodiversity, biology (e.g. life cycles) and structure of protists. Examples are the highly specific associations of termite flagellates and their bacterial ectobionts. In collobaritive proejctes I study host specificity and phylogeny of the symbiotic interactions between protists and prokaryotes.
