Research Interests
My primary research interest lies in animal communication and signalling behaviour. I am currently a postdoctoral researcher, investigating chimpanzee communicative behaviour within a cultural framework to contribute to our understanding of the behavioural flexibility of these animals. This work is conducted as part of the Pan African Programme: The Cultured Chimpanzee. My doctoral thesis investigated wild chimpanzee acoustic communication, where I also helped to develop a novel method for using vocalizations and auditory signals as a monitoring tool for primates living in a tropical rainforest. I continue to be interested in bridging the gap between behavioural research and applied conservation and hope to continue working on non-invasive monitoring methods.
