We undertake research to assist criminal investigations using a behavioral science approach. We have recently carried out studies primarily on hostage incidents and offender profiling.

Research on Hostage Incidents

Risk assessment of hostage incidents using databases
Based on the data from previous criminal cases, we assess the risk of death or injury to hostages and/or police officers in order to choose the best way to solve the criminal cases.

We carry out behavioral scientific research on hostage-barricaded incidents, kidnapping, hijacking incidents, and so on. We study the psychology of offenders and victims, negotiation techniques, and strategies for solving crimes.

Research on Offender Profiling

Statistical profiling
Focusing on victim's characteristics, offender's behaviors at crime scenes and their behavioral consistency in the criminal database, we make inferences about the likely offender's profiles based on our statistical analyses

We conduct behavioral scientific research on serious crimes, including serial sexual assaults, serial arsons, and random street killers. With regard to these criminal offenses, we conduct studies to establish the ways of linking crimes and of identifying the offender's characteristics and residential locations.
