Stephanie joined the Department of Psychology at York University's Glendon College as Assistant Professor in 2019. Her academic research interests include social, social-cognitive, and forensic psychology, with a more recent interest in the psychology of teaching and learning.
She has earned her Bachelor of Science in Forensic Psychology from the University of Toronto and her Master's and Doctoral degrees in Psychology from Ryerson University. Her doctoral research addressed the reliability of alibi witnesses by examining social and interpersonal factors that increase the likelihood that an alibi witness will lie to protect a criminal suspect.
She then completed a SSHRC postdoctoral fellowship jointly held at the University of Ontario Institute of Technology and the John Jay College of Criminal Justice. The subject of this research included the impact of confession evidence on lay witness testimony, the impact of eyewitness evidence on alibi witness statements, and best practices for suspect and witness interviewing.
Stephanie also worked as a behavioural scientist at at small research market firm in Toronto. Over the years, she has conducted behavioural research in both academic and industry settings, using the processes and methodologies best suited to these very different contexts.
