The Max Planck Institute (MPI) for Psycholinguistics, Nijmegen, the Netherlands, is offering two fully-funded PhD student positions in comparative bioacoustics/seal pup vocal development/evolution of speech/music cognition within the newly established Comparative Bioacoustics Group. The host research group, led by Dr. Andrea Ravignani, investigates the evolutionary bases of speech and music, mostly performing (non-invasive) cross-species behavioral research in seals, humans, and other mammals. The group has an international spirit and is open to diverse perspectives and approaches.
