Biography

I hold BA (2005) and MA (2012) degrees in Psychology from the American University of Beirut, Lebanon. In 2014, I joined the Erasmus Mundus Joint Doctorate Programme in Legal Psychology. I was supervised by Professors Aldert Vrij and Lorraine Hope and Dr. Samantha Mann at the University of Portsmouth and by Professors Pär Anders Granhag and Leif Strömwall at the University of Gothenburg. I completed my PhD in September 2017 and continued working in Prof. Vrij's research lab. I have been working since then on different projects funded by the Centre for Research and Evidence on Security Threats (CREST) and by the High-Value Detainee Interrogation Group (HIG).

Research interests

My doctoral thesis project examined various interview techniques that enhance lie detection in forensic contexts. I was specifically interested in interview techniques that elicit differences in statement consistency between lie tellers and truth tellers. I continue to examine novel interview techniques and how they affect the elicitation of verbal cues. I am specifically interested in the effects of sketch-based interviews and of opinion-based interviews on different types of details (e.g., PLATO details, complications).
