Research interests

The current research of me and my group focusses on three topics:

  • Kin recognition and kin selection
  • Development of social behavior
  • Understanding the influence of the biotic and abiotic environment on the evolution of cooperative breeding systems

To elucidate these topics we use a range of aquatic species like three-spined stickleback (Gasterosteus aculeatus), zebrafish (Danio rerio), or gammarids (Gammarus pulex). However, our main study system are cooperatively breeding cichlids.
