The Forensic DNA Division of NFS is a leading DNA profiling organization in South Korea, which has been trusted internationally, and has played a role in providing definite clues to various incidents and accidents including identity confirmation. Additionally, it carries out research in various fields with the introduction of the latest forensic scientific techniques in line with the status of the world's best DNA profiling organization.

Due to changes in the domestic and international social environment and the development of the Internet, types of toxic substances, substances of abuse and foods are becoming diverse, and the need for safety management is gradually increasing. In order to efficiently cope with constantly changing analysis demands, not only reliable analysis techniques should be developed, but new technologies should also be applied to existing analysis techniques to make them more sophisticated. For this purpose, the Forensic Toxicology Division is carrying out various research projects.

The Forensic Chemistry Division conducts tasks to provide important clues for the identification of the cause of an incident or the cause of death by reviewing the results analyzed with the latest precise instruments from various aspects, and at the same time, performs research to construct a database for establishment of new precise analysis methods to analyze on-site evidence rapidly and accurately and interpretation of results.

With the advancement of industrial technology, related facilities are becoming larger and larger and safety accidents are also becoming larger, threatening the lives and property of people. Crime cases are becoming more diverse and advanced, which requires advancement of analysis techniques.
Accordingly, the Forensic Safety Division performs research and development for safety accidents, fire investigations, firearms, explosives, tool marks, footprints, fingerprints, and bloodstain patterns.

Digital forensics is a field to conduct research on digital data stored in various forms and information that can directly or indirectly confirm biometric information such as facial features, gait, voice, handwriting., etc.
It also performs research on forgery detection for various types of records, cultural assets, artworks, and data stored as digital information, including outputs and printed materials, and research on analysis techniques using artificial intelligence.

In order to clarify the causes of traffic accidents for national safety and traffic safety advancement, the traffic accident analysis division has been performing research to establish analysis techniques for the identification of the cause of death by analysis and interpretation of the data recorded at the time of a traffic accident of the vehicle with DTG and EDR installed in accordance with the mandatory installation of Digital Tacho Graph in Article 55 of the Traffic Safety Act and mandatory disclosure of information recorded in EDR (Event Data Recorder) in Article 30 (2) of the Enforcement Rule of Automobile Management Act.

Psychological forensic refers to performing examinations to provide assistance for solving cases by determining the authenticity of the statements of people involved in an incident with regard to the investigation, analyzing psychological characteristics and enhancing the memories of victims and witnesses. The psychological forensic division carries out research on development of analysis techniques and equipment to increase the accuracy of psychological forensic analysis.

With the advancement of industrial technology, advanced medical devices such as PMCT (Postmortem Computed Tomography) have been applied to autopsies and have provided a great help to diagnose the cause of death. As it is necessary to develop technologies that can apply rapidly developing radiology, molecular biology, etc. to diagnosis the cause of death, interpret level of damage, and confirm identity, the research to apply various fusion techniques to the identification of the cause of death and interpretation techniques for human injury is in progress.
