I am an experimental psychologist largely interested statistics and perception. My teaching interests centre around the theme of the conjectural nature of knowledge. My current research interests focus on the visual information that contributes to threat appraisals. For a brief biography in stanzaic form, click on the About Me link on the sidebar.

Threat Perception, Image Statistics, Visual Psychophysics, Face Perception, Cognition
As of late, I have been interested in identifying the basic visual information that underlies inferences of threat. For example, when judging whether or not a stranger, object, or environment is dangerous , we presumably rely on some form of visual information. The aim of my research is to precisely determine what that information is. As a preliminary step to doing so, I am relying on visual artefacts that unambiguously attempt to communicate the presence of threat, such as angry faces, horror movie posters, metal album covers, and horror video game box art.
My early research was largely situated in the problem space of face identification. I have used experimental (i.e. psychophysical and metamemory paradigms) and computational (i.e. artificial neural networks and ideal observers) approaches to study how faces and associated autobiographical information are encoded, monitored, and retrieved. My research in this area has led to several peer-reviewed publications, government grants, and an award from the Canadian Psychological Association.
