A forensic science job description may appear distinctly different depending on the area of forensic science being practiced. This is because forensic science is a rather broad field and thus encompasses a number of specialties, all of which are rooted in the natural sciences.
Forensic science work generally involves one or more areas of science:
Chemistry: Involves the study of paint, chemicals, and similar substances and compounds
Biology: Involves trace and DNA evidence, including blood, hair, fibers, etc.
Drugs/toxicology: Involves testing for the presence or absence of drugs, alcohol and poisons in blood, urine, and tissues samples
It may also involve specific subspecialties of forensic science, such as botany, anthropology, and odontology (dentistry).
A forensic scientist may therefore take on one or more of the following forensic science jobs:
Questioned documents examiner
Trace evidence analyst
