Forensic Biologist

Job Description


Examination of blood and other bodily fluids, hair and bones are carried out by forensic biologists. These examinations serve a number of different purposes depending on the situation, but they are mostly done to help identify victims and aid criminal investigation.

The examination is not restricted to human beings. These tests can be carried out on insects, plants and animal remains as well.

Forensic biologists are up to date with the latest in laboratory technology. They use the technology to determine the time and the cause of the death.

Forensic biologists can choose to become experts in forensic entomology, forensic botany, forensic pathology, DNA analysis, biological chemistry and forensic anthropology.




Forensic biologists work alongside criminal investigations to provide evidence that would otherwise go undetected by performing analyses on biological evidence found at a crime scene, including:

  • DNA testing of suspects and comparing it to DNA found at the scene.

  • Blood testing of victims to determine if any drugs or toxins played a role in the cause of death.

  • Performing tests submitted by law enforcement agencies, including infrared spectroscopy, mass spectrometry, and electron microscopy. 

Part of their work involves maintaining detailed logs and writing detailed reports about their discoveries during the examinations.

They must exercise great attention to detail since the smallest of mistakes can derail the investigation. Administrative duties they are responsible for include:

  • Guaranteeing that all protocols and regulations are followed and maintained.

  • Collecting and inputting data into relevant program databases.

  • Preparing written reports regarding evidence.

  • Bridging the gap between the forensic laboratory team and crime scene investigators.

  • Developing and maintaining high quality operating procedures.

In addition to aiding criminal investigation, forensic biologists are known to assess environmental contamination and evaluate threats to public health.

Working Conditions


The work of a forensic biologist can be messy and unpleasant. Field work can be particularly distasteful as it often involves collecting and examining biological materials.

This may require collecting material in the advanced stages of decomposition by digging through trash, mud, or debris.

The work of a forensic biologist can be repetitive and tedious at times. However, most find great satisfaction in finding the critical piece of the jigsaw puzzle in a highly important criminal investigation.
