Welcome to the Max Planck Institute for Chemical Ecology

We investigate how organisms interact with chemical signals.

Slogan “Wir treten ein für ein weltoffenes Thüringen" (in English: We stand for a cosmopolitan Thuringia”) with colorful overlapping shapes.

We support the Initiative “Weltoffenes Thüringen”.

We are committed to ensuring that people from different backgrounds live and work together in a respectful manner.
