Eduardo Lorenzo Pérez-Campos

Eduardo Lorenzo Pérez-Campos is affiliated with the Tecnologico Nacional de Mexico (National Technology of Mexico) at the Instituto Tecnológico de Oaxaca (Oaxaca Institute of Technology) in Oaxaca, Mexico. He works in the División de Estudios de Posgrado e Investigación (Division of Graduate Studies and Research). While his primary background appears to be in bioengineering and biochemistry, he has developed a significant body of work in deception detection and investigative interviewing techniques, with a particular focus on their application within the Mexican criminal justice system.

Pérez-Campos has contributed substantially to foundational research in deception detection methods and investigative interviewing. His work includes innovative applications such as the use of interview techniques to detect deception and explores investigative interview models that highlight the benefits of using verbal approaches to detect deception. His 2024 study traces the evolution of credibility assessment from ancient methods to modern techniques, examining their scientific validation and practical applications. His research addresses the critical gap in training within Mexican governmental institutions responsible for investigating crimes, highlighting the need for techniques that obtain objective and reliable information while guaranteeing the protection of fundamental rights. He has written extensively on the Cognitive Interview, Strategic Use of Evidence (SUE) technique, and the Conversation Management Approach, particularly in challenging contexts such as feminicide investigations in Mexico.

His work demonstrates a strong collaborative approach, frequently publishing with a close team of co-authors including Eduardo Pérez-Campos Mayoral, as well as internationally renowned experts in investigative interviewing such as Ray Bull, Pär Anders Granhag and Maria Hartwig, Ronald Fisher, and Mark Fallon. Due to his background, he collaborates with biomedical research groups, credibility assessment and investigative interviewing parties. All of his deception detection and polygraph-related publications appear in the peer-reviewed journal European Polygraph, making him a consistent contributor to that publication between 2022 and 2025.

Pérez-Campos represents an interdisciplinary researcher bridging multiple fields. While maintaining active research in biomedical sciences and biochemistry, his investigative interviewing work connects psychological science, forensic investigation, and human rights concerns. His research has particular relevance for Latin American contexts, where he advocates for evidence-based interviewing methods as alternatives to coercive interrogation techniques and seeks to improve investigative practices in cases involving serious crimes, particularly violence against women.
