Generally speaking, my research examines how we perceive human faces. I'm interested in how we recognise faces and emotional expressions, make first impressions from facial appearance, and perform identity matching tasks. My work also examines that factors that help or hinder performance on these types of tasks. Other research interests include the lateralisation of visuospatial attention, and ensemble coding.
My current research includes investigating how COVID-19 face masks affect identity and emotion recognition, how we make first impressions of faces in naturalistic social scenes, and how humans perform face recognition and matching tasks when working with automated facial recognition systems.
Honours Projects 2023
I'll be offering several honours projects in 2023, all revolving around human performance on one-to-one face matching tasks (potentially when assisted by facial recognition technologies). These tasks are common in every day life, such as when you are asked to show photo ID (e.g., a driver's licence) at a store or when travelling through airports. Yet humans struggle to decide whether photo ID matches the person presenting it for inspection! Even under ideal lab conditions, participants often only achieve accuracy of around 80% (or, to put it another way, make a mistake 1 in 5 times). You can find links to my most recent work in this area through the link to Google Scholar on my profile (below).
If you are interested in some other aspect of face perception, please know that I am also open to projects suggested by students.
In either case, please contact me via email for further information.
