Co-workers at the Work & Party Day

Welcome to the Max Planck Institute for Chemical Ecology

We investigate how organisms interact with chemical signals.

We support the Initiative “Weltoffenes Thüringen”.

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