I received my bachelor's degree in Applied Psychology from University College Cork in 2008, and in 2011 I completed an MSc in Evolution and Behaviour at the University of Stirling.
Following my MSc, I went on to complete a PhD in comparative psychology at Stirling under the supervision of Prof Christine Caldwell, graduating in 2016.
In 2014 I became a part-time lecturer at Newbattle Abbey College, before taking-on my current post as an Early Career Fellow in 2015. I am a member of Stirling's Behaviour and Evolution Research Group, and the Scottish Primate Research Group.
I am the module coordinator for the 2nd Year module, The Social Mind (PSYU9A3). I also lecture on first year (PSYU911/PSYU912), third year (PSYU9AJ), and MSc modules (PRMP131).
I am broadly interested in the study of comparative cognition with a particular interest in mechanisms of social learning and social influence. My PhD research examined automatic imitation in capuchin monkeys and children, as well as behavioural and emotional contagion in nonhuman primates. I am also interested in understanding how imitative ability might develop in human and nonhumans primates.
