Senior Lecturer

My interest in the mechanisms and evolutionary explanations of face perception is the result of my diverse academic background. My undergraduate degree was the interdisciplinary life sciences programme, BSc (Hons) Human Sciences at University College London (UCL), where my main interests were in evolution, genetics and psychology.

I went on to study for an MPhil in Biological Anthropology at the University of Cambridge, where I first began research on the evolutionary psychology of face perception. I completed my PhD with Prof David Perrett at the University of St Andrews in 2009. I then held an ESRC Postdoctoral Fellowship at the University of Bristol, before moving to the University of Nottingham Malaysia Campus as an Assistant Professor of Psychology in 2010. I joined Macquarie University as a Senior Lecturer of Psychology in February 2014.

Research interests

My research focuses on face perception, which I approach from two main angles. First, I am interested in the interaction between health and facial appearance. How does our health impact on the appearance of our faces and bodies, and how are these changes perceived by observers? Second, I am interested in the similarities and differences in face processing style between people from different ethnic groups and cultures. We know that people from different backgrounds look at faces in different ways, but to what extent does this reflect different cognitive processing styles?
