My research involves investigating the role of vocalisationsin animal communication. My past research has looked at examining vocal recognition in seals and decoding the important acoustic features used in this system.
Currently my research is focused on trying to understand phenotypic plasticity in signal structure with changes in the environment. To do this I will be examining the acoustic behaviour of blue whales and the associated changes in their environment. These whales are highly vocal, long lived and display phenotypic plasticity in their vocalisations, making them a good species to study. It was recently discovered that the song produced by blue whales is changing in frequency and that this change is occurring globally. One of my research objectives is to understand the mechanisms driving this and other changes in signal structure.
