Brent Snook is a University Research Professor in Psychology at Memorial University of Newfoundland. He holds a PhD in Psychology from The University of Liverpool, UK. His research involves an examination of the reliability and validity of investigative practices (e.g., interviewing, deception detection). Currently, he is exploring the most effective ways to ensure adults and youth understand their interrogation rights and is developing and testing investigative interviewing techniques (e.g., note-taking, sketching). His applied work involves the implementation of the PEACE model of interviewing in North America. Brent's work has led him to collaborate with academic and professional bodies in The United States of America, The Netherlands, England, Germany, and Canada.

Brent also serves as an expert witness on interviewing and memory contamination in court and provides legal advice on the integrity of evidence derived from interviews and interrogations. Brent also provides training on scientific-based information gathering techniques to a wide variety of groups such as police organizations, government departments (e.g., health investigators), non-profit groups (e.g., public defenders), and large, private sector organizations (e.g., oil companies). He is also a research  (e.g., survey/instrument development, data analysis, report writing) and organizational behaviour consultant (e.g., conflict and performance).

Together with Todd Barron, he has now instructed hundreds of practitioners around North America on evidence-based interviewing practices.

He has a Master of Science degree in Experimental Psychology from Memorial University, and an undergraduate degree from Memorial University with a major in Police Studies and a minor in business. His policing background includes training as a polygraph examiner, work in the area of Major Crimes, as well as being in charge of his departments’ Investigative Interviewing Unit.
