Catherine (Cat) Hobaiter is a British-Lebanese Primatology focusing on social behaviour in wild chimpanzees and involved in long-term studies of chimpanzees in the Budongo Forest Reserve in Uganda and the MoyenBafing National Park in Guinea. She is particularly interested in the role gestures play in communication. She is a Reader at the University of St Andrews.
Career
Hobaiter is based at the University of St Andrews but spends considerable amounts of time on field research in Uganda. She gained tenure in 2013.
Her undergraduate degree started her interest in comparative behaviour and contact with Richard Byrne from St Andrews University led to her first four months fieldwork looking for baboons in Budongo Forest Reserve, working from the Budongo Conservation Field Station.[
]
Her work has studied the use of gestures in communication by great apes, especially chimpanzees, in the wild. This requires filming gestures for detailed analysis and, prior to her work, this had been undertaken primarily in zoos or wildlife parks.[ Her studies have gradually developed a catalogue of around 80 gestures that form a language common to several groups of wild apes, measured in terms of 'apparently satisfactory outcomes' (ASO) after assessing many records.][ A citizen science project showed that some of the gestures are also understood by humans.][
]
The film recordings also revealed other aspects of chimpanzee life, such as adoption of new tools for drinking.
Her research now focuses on how human language evolved, through studying the use of gestures in both humans and great apes.[

Personal life
Catherine (Cat) Hobaiter initially lived in Lebanon, returning to the UK when she was a child.
