Personal profile


Teresa joined the Psychology and Behavioural Sciences department as a lecturer in Forensic Psychology in September 2014. She completed her undergraduate and Masters degrees in Clinical Psychology in Portugal at the University of Coimbra. Her longest work experience (12 years) was at a prison for young male offenders where she worked as a psychologist with prisoners, both individually and in group. She completed a PhD in Forensic Psychology in July 2014 at the University of Birmingham on multiple perpetrator rape (MPR). In this PhD, lone and MPRs were compared, and simultaneously the effect the number of perpetrators involved in MPRs has on offence characteristics was examined. Additionally, cross-cultural differences between MPRs committed by juveniles in Portugal and the Netherlands were examined. Furthermore, a qualitative study was carried out which analysed the reasons and motivations given by convicted perpetrators of MPR for participating in the offence. Teresa has published some papers in international journals and contributed with a chapter in the first book on MPR. She has also presented her research in national and international conferences. Her research in this area is ongoing and currently she is completing a study on leadership in MPR and has recently interviewed UK offenders convicted of this crime.

Vision Statement

Coming from a practitioner background I’m interested in research that has practical implications and can be used to inform practice. Likewise, I strongly believe that practice should be evidence based which led to my interest in researching multiple perpetrator sexual offending. While working with offenders convicted of this crime, I felt the need to better understand this type of offending in order to effectively address the offenders’ treatment needs. From there my research interests expanded to include group and juvenile offending. Ultimately, I wish to develop research that can be used to inform prevention and intervention programmes for different types of offenders.
