I am interested in animal communication systems, and specifically in the cognitive capacities of receivers to extract information that goes beyond the perception of the signaling context. After a master thesis on meerkats’ social cognition, my current research focuses on the evolution of vocal communication in the Archosauria. I am investigating the potential of honest acoustic signals in American and Chinese alligators (Alligator mississippiensis/sinensis), as well as the abilities of common ravens (Corvus corax) to perceive syntactical changes in the structure of vocal duets. Research on these extant Archosaurians may even provide insight into the communication of extinct dinosaurs.
