Assistant Professor, University of Twente

Simon is Assistant Professor at the department of Psychology of Conflict, Risk and Safety at the University of Twente, the Netherlands. Simon is an experimental psychologist who is particularly interested in developing novel measures for studying intelligence gathering interactions in controlled settings. His work is mainly focused on intelligence gathering, with a specific interest in subtle elicitation tactics, trust-building strategies, evidence disclosure approaches, and behavioral adaptability.

Simon has completed four full-scale research projects during his Ph.D. candidacy and post-doctoral positions (all financed by the High-Value Detainee Interrogation Group). These projects include information gathering strategies (i.e., the Scharff technique) and relationship building methods (i.e., trust-building tactics) in the interrogative context, and an examination of real undercover interactions. In 2018, Simon received the EAPL early career award. He has published ten papers in peer-reviewed journals and is a regular speaker around the world. Simon is very keen on the applied value of his work and has already established relationships with practitioners in a number of countries, including the US, the UK, Scandinavia, the Netherlands, and South Korea.
