    Prof. Galit Nahari is the head of the Department of Criminology at Bar-Ilan University, Israel, and the editor of Legal and Criminological Psychology. Her main research interests are legal and investigative decision-making, applied memory, detection of deception and witnesses credibility assessments. As part of it, she develops interrogation and lie-detection methods (prime example is the Verifiability Approach), examines their validity and suitability in different contexts, and their vulnerability to judgmental biases. A major part of her research further focuses on the cognitive processes underlies credibility and veracity assessments, as well as on individual differences which impact these assessments.
