Joel Suss, Ph.D.,Joel Suss, Ph.D., is an assistant professor of Psychology (Human Factors) at Wichita State University, Kansas. His research focuses on human performance and cognition in complex, dynamic, and often stressful operational settings. He has conducted decision-making research with police officers, pilots, and wildland firefighters. His approach seeks to identify and define expertise in operational settings, understand the perceptual-cognitive basis for expertise and skilled performance, and design and validate solutions to mitigate error, accelerate training, and improve resilience. Joel has a keen interest in use-of-force training, firearms safety, defensive tactics, police use of body-worn cameras, and sustained attention tasks (e.g., monitoring multiple CCTV surveillance cameras, conducting a stakeout). He is often dismayed by the lack of scientific research that addresses issues that police trainers and administrators face on a daily basis. Therefore, he is committed to supporting law enforcement by conducting use-inspired research that applies scientific principles and theories to inform police training and operations.

Laura A. ZimmermanLaura A. Zimmerman, Ph.D. is an experimental psychologist with specialization in law enforcement decision-making, practices, and training. She has spent over 15 years conducting research to characterize decision making during high-stakes critical incidents, with extensive experience working with law enforcement and military. She also specializes in investigative interview and interrogation research. Her focus is on developing realistic research and training scenarios and investigating real-world police practices in field settings. To gather research data, she has conducted extensive interviews, focus groups, surveys, and ride-alongs with local and federal law enforcement officers. In addition, she has taught a module on police decision making at the Force Science Institute Law Enforcement Certification Course and is a regular contributor to ILEETA’s Use of Force Journal. She is dedicated to contributing scientific findings to the development and refinement of evidence-based police practices. Email Laura at This email address is being protected from spambots.

There is a fundamental need for law enforcement agencies to acknowledge human capabilities in policy, procedure, tactics, and training. This cultural shift enables law enforcement to fall in line with other high risk occupations such as the airline, transportation and medical industries. Recommendations for Human Factors applications in policing come from the International Association of Chiefs of Police, The Police Executive Research Forum, International Law Enforcement Educators and Trainers Association, the Law Enforcement Executive Forum, and the National Institute of Justice (to name a few!).
