Careers in Forensic Science

Lara Antal

The term "forensic scientist" doesn't describe a single job title, but rather a host of scientific specialties that apply expertise to legal questions. "Forensics" means "of or having to do with questions of law," so nearly any discipline can be considered "forensic" if it's applied to solving crimes or to the court system. Wherever your interests lie, there's likely to be a discipline that fits you.

Deoxyribonucleic acid analysis (DNA) is gaining more and more prominence in criminology and forensic science. DNA contains the genetic coding that makes us...well, us. It's believed to provide an as-close-to-perfect identification as possible, far more accurate than fingerprinting.

DNA analysts compare DNA samples taken from suspects and victims to determine whether someone was present at a crime scene, whether they were involved in a violent encounter, and other questions of identity when a sample is available. DNA analysts can also compare unknown samples to databases to identify potential suspects.

DNA analysts can expect to earn an average of about $64,000 a year, BLS reports.

Polygraphs have limited admissibility in courts, but the polygraph exam remains a useful tool in solving crimes and detecting deception from suspects and witnesses.

Polygraph examiners are trained to conduct examinations using the "lie detector" and to provide analysis of the results. Polygraph examiners undergo lengthy training to hone their skills, and they're often used in internal administrative investigations of law enforcement personnel.

Polygraph examiners might work for criminal justice agencies or as private contractors. Their services are quite often employed during the candidate screening process for many sensitive jobs. '

Polygraph examiners earn around $95,000 a year on average, according to the 2019 ZipRecruiter database. PayScale's database sets a lower average of $52,230. (Both are self-reported.)

Forensic documents examiners compare handwriting samples and use their expertise to identify forgeries of contracts, checks, bank statements, and other documents and electronic records. They can also determine the validity of a signature through handwriting analysis and even determine the relative age of a document.

A forensic documents examiner must undergo an apprenticeship to learn the trade, and she might be employed by private contractors or government agencies. Forensic documents examiners most often assist in white-collar crimes and work with digital experts and forensic accountants.

Salary and earning potential for these experts can vary significantly depending on the employer and level of expertise. ZipRecruiter self-reports average $47,044—ranging from $16,000 to $109,500.

The ancient Greeks were the first to note the various signs and symptoms of poisons, and they were the first society known to uncover murders from poisoning due to this ability.

The field of toxicology has developed and evolved significantly since that time. Today, forensic toxicologists help investigators identify the causes of death that include poisons, chemicals, and intoxicating substances. They assist in the prosecution of DUI and DWI arrests and can detect the presence of drugs or alcohol in a suspect or victim's blood.

Aspiring toxicologists should have a firm grasp of chemistry, biology, or both, as well as knowledge of pharmacology. ZipRecruiter's self-reported average salary is $85,670—ranging from $25,500 to $152,000.

Grisly crimes and cold cases call for the expertise of someone who specializes in identifying human remains. Anthropologists can determine the age, sex, and weight of a victim by studying decomposed physical remains and skeletal systems, as well as the types of injuries the victim received and the potential cause of death in many cases.

Forensic anthropologists often work at colleges and universities and provide assistance to law enforcement entities on an as-needed, contractual basis. They generally hold a master's degree or a doctorate in physical anthropology and can expect to earn a median salary of about $62,000 a year, according to BLS.

Sometimes DNA identification is impractical and fingerprint analysis is impossible. Forensic odontologists use unique dental features to identify human remains when particularly gruesome crimes occur or after mass casualty events. They can also analyze bite marks and compare them to samples to help identify victims and suspects, as well as help investigators, determine whether injuries are defensive or offensive.

Forensic odontologists have doctorates in dental surgery or dental medicine and they usually practice general dentistry and perform forensics services in addition to their dental practices. Forensic odontologists earn between $150,000 and $180,000, according to the American Dental Association.

An arson investigator uses residue, ash, and other substances left after a fire to pinpoint whether such an event was intentional arson or the result of an accident. They might be called on scene to analyze the behavior and characteristics of fires while they're still in progress. An arson investigator's science is flames.  

The education required for a career as an arson investigator is on par with that of police officers. You don't necessarily need a college degree, although it would certainly enhance your resume, particularly if you choose a criminal justice-related major or one in the field of fire science or chemistry. Mean pay is about $64,000 annually, according to BLS.

What Job Is Right for You?

Forensic science careers can be rewarding and challenging, and they're not limited to these profiles. As times change, investigative needs change, so this list is by no means encompassing.
