Forensic Experts India

What do Forensic Experts do?
Forensic scientists perform two roles in their work. One is to analyze physical evidence found either on a victim, at the scene of a crime, or both and to compare it to evidence found on the suspect. The other is to provide expert testimony in a court of law. This article describes what forensic scientists do, where they work, what they earn, and how they train. It also provides sources of additional information.

Forensic science draws on, and brings together, many scientific disciplines. Chemical tests, identification of hair, blood, dirt, cloth fibres - DNA testing, microscopy, spectroscopic analysis, forensic psychology and forensic medicine - all contribute to integrated analysis of a crime and the physical evidence left at a crime scene. While forensic science has been a feature of many schools’ senior multi-strand science, it can also be a real-life context for learning in the other senior sciences - and it can certainly be a stimulating and life-like context for learning science in all the years of schooling.

A forensic scientist may perform the following tasks:

identify illicit drugs
analyse drugs and poisons in human tissue and body fluids including blood alcohol results
examine and compare materials such as fibres, paints, cosmetics, oils, petrol, plastics, glass, metals, soils and gunshot residues
examine items of human and animal biological material to be compared with victims and suspects using DNA profiling
conduct botanical identification of plant materials at trace levels, and whole-plant identification such as cannabis
conduct document examinations, both physical (e.g. handwriting, typewriting) and chemical (e.g. analysis of inks and papers)
examine crime scenes
identify firearms and ammunition (forensic ballistics)
detect, enhance, recover and identify latent fingerprints, footprints, tool marks, shoe marks, tyre marks and tracks
examine fire and explosion scenes to establish the origin and cause
enhance and analyse audio recordings
produce reports, appear in court and present scientific and/or opinion testimony accurately and in a manner which is readily understood by the court
make presentations to a wide variety of audiences on the work of forensic scientists
liaise with, and provide advice to, police investigators, scientists and pathologists across a broad range of disciplines.
