The main focus of my research is on the neuronal basis of spatial orientation in insects, specifically on sky-compass orientation. I am particularly interested in how different sky-compass signals, like the sun’s position, the polarization pattern and the color gradient of the sky are integrated and weighted, and how the processing in the brain is adjusted in the course of the day according to the changes in solar position.
