Peter Ejbye-Ernst

Peter Ejbye-Ernst is a Senior Researcher at the Netherlands Institute for the Study of Crime and Law Enforcement (NSCR), specializing in behavioral analysis of policing, interpersonal conflicts, and public safety. His work employs video-based interaction ethology to study real-world aggression, de-escalation, and third-party interventions.

• Focus Areas: Police use of force, urban violence, bystander behavior, and policy impact during crises like the COVID-19 pandemic.
• Methods: Systematic video observation, ethogram development, and behavioral coding.

Key Trends: His publications analyze how environmental interventions (e.g., lighting changes) affect drug markets and public disturbances, alongside exploring biases in law enforcement practices such as stop-and-search profiling. Collaborations with the Video Violence Group highlight interdisciplinary efforts to bridge criminology, sociology, and ethology.
