After completing her PhD in Behavioural Neuroscience at the University of St Andrews in 2002, Dr Walker spent 6 years as a Research Associate in the Department of Experimental Psychology at the University of Cambridge where she studied the neural and neurochemical basis of executive control behaviours mediated by the prefrontal cortex. Subsequently she spent 3 years working as a research scientist for Unilever R&D in Port Sunlight; here her role involved managing and developing external collaborations with academics in cognitive psychology and neuroscience, as well as leading internal research in human olfaction. She returned to academia, to take up her current position, in November 2011. Her research is focused on how exposure to biologically salient sensory stimuli influences emotional and cognitive behaviour. She is a member of the Somatosensory & Affective Neuroscience group at LJMU and Co-I on a Leverhulme Trust Funded project investigating the role of 5-HT in psychological responses to affective touch.
