Eduardo Lorenzo Pérez-Campos

Eduardo L. Pérez-Campos is affiliated with the Department of Graduate Studies and Research at the National Technology of Mexico (TecNM)/Instituto Tecnológico de Oaxaca (IT.OAXACA) in Mexico. He serves as the representative of Forensic Interview Solutions in Latin America (LATAM), working to promote evidence-based investigative interviewing techniques in a region where such approaches are still emerging. He frequently collaborates with Eduardo Pérez-Campos Mayoral, a researcher at the Autonomous University "Benito Juárez" of Oaxaca, and together they form a productive research partnership focused on deception detection and credibility assessment.

Pérez-Campos has contributed to the historical and theoretical understanding of deception detection methods, analyzing characteristics such as the period in which various methods were used, their scientific validation, and their passive or active approach. His work has examined how historical approaches established theoretical foundations for modern technologies, such as the Bisha Bedouin Court System (ordeal by fire) based on arousal theory, as well as innovative applications such as the use of interview techniques to detect deception. His 2024 study with colleagues traced the evolution from ancient oracles to modern techniques, while highlighting the benefits of using verbal approaches and investigative interview models to detect deception. His 2025 work on the Strategic Use of Evidence (SUE) technique represents a method of scientific interrogation that entails the strategic management of case information and evidence.

Pérez-Campos has noted that in Latin America, the investigative interview is still in its beginnings, with most public and private investigators using interview and interrogation techniques aimed at obtaining admission or confession, instead of applying Investigative Interview techniques focused on information gathering. His research collaborations include work with internationally recognized experts such as Pär Anders Granhag, Maria Hartwig, Mark Fallon, Ray Bull, and Eric Shepherd, positioning him within a network of leading deception detection and investigative interviewing scholars. His 2023 study applied the Conversation Management Approach to feminicide investigations in Mexico, demonstrating practical applications of evidence-based interviewing to serious crimes.

Pérez-Campos's work bridges the historical study of deception detection with contemporary applications in criminal investigation. His stated objective is to provide Latin American interviewers with information on best practices used in other countries, to raise awareness of the need for training in this area, noting that correct application of investigative interview techniques is essential to investigate crime. His publications in European Polygraph demonstrate his contributions to understanding both the evolution of psychophysiological detection methods and the advantages of cognitive, verbal-based approaches to credibility assessment over traditional arousal-based techniques.
