Interests

I am interested in the complexity underlying vocal communication and cognition in animals. By taking a broad comparative approach focusing on both primate, non-primate mammals and birds in the wild and captivity, we aim to unpack the similarities and differences between animal and human communication and ultimately what selective conditions might have been responsible for the evolution of the human language faculty.

Research Themes

Comparative psychology, comparative linguistics, language evolution, syntax, phonology, semantics, animal behaviour, animal cognition, primates, non-primate mammals and birds.
