Focus of Research
My research interests involve the study of normal and abnormal visual perception. My primary research in the Social Perception Lab is aimed at studying Developmental Prosopagnosia in children. Developmental Prosopagnosia (DP) is the inability to recognize faces without any known brain injury or anomaly, a condition that is estimated to affect about 2% of the general population. Research on DP with adult participants has led to important findings about the cognitive, neural, and genetic bases of DP, yet little has been done to study this condition in children. This is surprising given that DP is due to a failure to develop the mechanisms necessary for face recognition and therefore emerges early in life. Critically, the study of DP in children will allow us answer important questions about abnormal and normal face perception. Learning about the etiology and progression of DP may also lead to deeper understanding of other selective developmental deficits such as dyslexia, dyscalculia, and specific language impairment. Three primary goals of my research on childhood DP are to 1) develop diagnostic tools, 2) study its developmental trajectory, and 3) identify and treat individuals with DP.

My other research projects include 1) investigations of the neural mechanisms of face processing through the study of adults with acquired prosopagnosia, 2) the study of scene perception in Bálint syndrome, 3) the study of other neuropsychological cases related to abnormal visual perception (e.g. prosopometamorphopsia).These projects are being conducted in collaboration with my PhD supervisors at the University of British Columbia: Dr. Alan Kingstone and Dr. Jason Barton
Tests of Face Perception for Children and the Dartmouth Database of Children's Faces (DDCF)
During the process of developing tests of face perception for children, we took photos of over 120 children. These children posed 8 different facial expressions and were photographed from 5 different camera angles, under controlled lighting conditions. These facial expressions were rated for their believability by 20 independent raters. The top 40 female and 40 male models were included in a freely available database for use in research studies.
