What do we do ?

Our team is dedicated to the study of vocal communication processes of animals in their natural environment. We use a multi-disciplinary approach :

  • Signal processing and Big data analysis (sound analysis & synthesis software, noise extraction methods, localisation, Machine learning,…)
  • Animal behavior and Cognition (use of acoustic/visual/olfactory lures to decipher recognition mechanisms, operant conditioning, multi-sensor tag attached to animals)
  • Imaging methods (MRI, Synchroton X-Ray)
  • Biological analysis (DNA, biochemical analyses such as GC-MS).

Our team belongs to the Department of Cognitive Neuroscience at the Paris-Saclay Institute of Neuroscience.
