Forensic Science Research & Development Strategic Research Plan, 2022-2026 Research & evaluation in publicly funded forensic laboratories Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law. NIJ’s forensic science research and development program focuses on basic and applied scientific research with the intent to: On this page, find links to articles, awards, events, publications, and multimedia related to forensic sciences. The word forensic comes from the Latin word forensis: public, to the forum or public discussion; argumentative, rhetorical, belonging to debate or discussion.

A relevant, modern definition of forensic is: relating to, used in, or suitable to a court of law. Any science used for the purposes of the law is a forensic science. The forensic sciences are used around the world to resolve civil disputes, to justly enforce criminal laws and government regulations, and to protect public health. Forensic scientists may be involved anytime an objective, scientific analysis is needed to find the truth and to seek justice in a legal proceeding. A forensic scientist is first a scientist. When a scientist's knowledge is used to help lawyers, juries, and judges understand the results of scientific tests, the scientist becomes a forensic scientist.

Because the work of a forensic scientist is intended to be used in court and because scientific evidence can be very powerful, the forensic scientist must be accurate, methodical, detailed, and above all, unbiased. In most cases, the item or items in question are provided to the forensic scientist for examination and analysis. In other cases, they may need to go to the scene to conduct an on-site analysis, gather evidence, or document facts for later analysis. Having been provided or having gathered the relevant information, the forensic scientist then has to decide which examinations, tests, or analyses are appropriate – and relevant – to the issue(s) in dispute. (Is that powder cocaine or not? Did a defect in the road surface cause the crash?).

They must conduct the most appropriate tests/analyses and document the process to interpret the results and document the steps followed to reach this conclusion or opinion. The forensic scientist will, at some point, have to testify. Testimony is the verbal statement of a witness, under oath, to the judge or jury. Forensic scientists are "expert" witnesses as opposed to ordinary or "fact" witnesses. Expert witnesses are permitted to testify not just about what the results of testing or analysis were ("facts"), but also to give an opinion about what those results mean. For example, a forensic scientist may testify about the observed, factual results of a chemical drug analysis and that, in their expert opinion, the results show that the tested substance is a specific drug,...

To qualify as an expert witness, the forensic scientist must have a solid, documented background of education, training, and experience in the scientific discipline used to conduct the examinations, testing, or analyses about which... Forensic science merges science and law to solve crimes and administer justice, providing objective evidence for legal proceedings. It includes disciplines like forensic chemistry, biology, and digital forensics. Key practices involve evidence collection, analysis, and expert testimony. Emerging technologies like AI and rapid DNA analysis are enhancing its capabilities. Forensic science is the intersection of science and law, involving the application of scientific principles and techniques to solve crimes and administer justice.

It encompasses various disciplines, each contributing to criminal investigations and legal proceedings. The primary goal is to provide objective evidence that can be used in court to support or refute claims made by the prosecution or defense. Forensic scientists follow Locard's Exchange Principle that "every contact leaves a trace". Learn more about Locard's Principle. Key elements of crime scene investigation include: With the rise of technology, digital forensics has become increasingly important:

The chapter “Introduction to Forensic Science” provides an overview of the diverse fields encompassed within forensic science, common types of evidence encountered at crime scenes, the seven principles of forensic science, and significant contributors... The chapter begins by outlining the multidisciplinary nature of forensic science, including its subdivisions such as forensic chemistry, forensic biology, forensic anthropology, and digital forensics. It emphasizes the importance of integrating various scientific disciplines in the investigation of crimes and the analysis of evidence. Additionally, the chapter discusses common types of evidence encountered in forensic investigations, including fingerprints, DNA, trace evidence, firearms and ballistics, and digital evidence. The seven principles of forensic science, including the Locard’s Exchange Principle and the Principle of Individuality, are presented to highlight the foundational principles guiding forensic investigations. Furthermore, the chapter recognizes major contributors in the field of forensic science from around the world, showcasing their significant contributions and advancements in forensic techniques and methodologies.

By providing an overview, this chapter serves as a foundation for understanding the principles and applications of forensic science.

J Indian Acad Forensic Med 38:77–79 Forensic science, at its core, is the application of scientific methodologies and technologies to matters of law. It’s a deeply interdisciplinary field, leveraging advancements in diverse scientific and technological areas to analyze evidence, reconstruct events, and ultimately, contribute to the pursuit of justice. While often associated with criminal investigations, its applications extend to civil litigation, regulatory compliance, and even national security. The study of forensic science involves a comprehensive understanding of scientific principles, analytical techniques, and legal procedures. Its practitioners must possess not only a deep understanding of their specific area of expertise, but also the ability to communicate complex scientific findings in a clear and concise manner suitable for legal professionals...

Forensic science doesn’t exist in a vacuum. It’s built upon a robust foundation of scientific disciplines, each contributing unique tools and perspectives. Understanding these foundational areas is crucial for anyone pursuing a career or simply interested in this fascinating field. The breadth of forensic science necessitates specialization. Professionals typically focus on specific areas of expertise, developing in-depth knowledge and skills within that domain. The impact of forensic science extends far beyond the confines of crime labs and courtrooms.

Its applications are diverse and critical to various sectors.

Forensic science is a set of scientific methods and expertise used to investigate crimes or examine evidence that might be presented in a court of law.

Forensic science comprises a diverse array of disciplines, from fingerprint and DNA analysis to the analysis of synthetic opioids and digital evidence. Forensic science plays a crucial role in our criminal justice system. Forensic science can help investigators collect, rapidly analyze, and interpret complex evidence to solve crimes, including cases that have long been unsolved. It can help exclude innocent people from an investigation or exonerate them in cases of wrongful conviction. And it can help juries as they make decisions that have enormous consequences on the lives of alleged perpetrators.
