Personal profile


Dr Nicholas Longpré is a Lecturer in the Department of Psychology at the University of Roehampton. He is the acting Program Convenor for the MSc Forensic Psychology. He also acts as Modules Convenor for the 3rd year BSc Criminal and Forensic Psychology and for the MSc Forensic Psychology.


Research interests

My research interests principally revolve around sexual and nonsexual violent offending. More specifically, my work focuses on the study of the latent structure and etiology of sexual sadism and sexually coercive behaviours, the Agonistic Continuum, the measurement of offence-supportive cognitions among sexual offenders, as well as the exchange and consumption of child pornography. I am currently studying the latent structure of sexual harassment and sexually coercive behaviours among college students and their correlates with personality disorders, hypersexuality, and emotion processing.
