Sonya's main research interests revolve around scientific assessments of animal welfare, in particular for zoo- and sanctuary-housed wild animals, and behavioural adaptations of animals to their environments, including free-living wild animals. A lot of her work is on non-human primates, especially great apes, but she also has research interests covering a range of other taxa; her research has direct and indirect implications for the conservation of species.
