My main research focuses on investigating the origin, structure and function of vocal signals in vertebrates, including humans.
I use an integrated, multilevel approach to address key questions on the function and evolution of vocal communication. I conduct and supervise observational and experimental studies on both captive and free-ranging species, such as deer, owls, herring gulls and domestic dogs. More recently I have started investigating the function of human vocalisations, as well as the expression and perception of gender and related attributes in the human voice.
