Forensic biologists examine blood and other bodily fluids, hair, bones, insects and plant and animal remains to help identify victims and support criminal investigations.
Using technology in the lab and in the field, forensic biologists collect and analyze biological evidence found on clothing, weapons and other surfaces to determine the time and cause of death.
They keep detailed logs and write reports about what they find. Attention to detail is critical, because a single mistake can cause the evidence to be thrown out of court. Senior-level forensic biologists may testify in court about their findings.
Forensic biologists may become experts in:
In addition to helping solve crimes, forensic biologists may investigate environmental contamination or other public health threats.
Working so closely with biological material (including every sort of fluid found in the human body) can be messy, smelly and generally unpleasant.
Field work can be particularly dirty work. At crime scenes, forensic biologists collect leaves, insects and other biological material and examine the victim’s clothing and remains (which may be in an advanced state of decomposition). They may sift through the surrounding dirt and even garbage looking for biological evidence.
In the lab, forensic biologists examine this evidence using microscopes and other technology. They photograph and catalog the evidence and perform DNA and other tests on the samples.
The work can be repetitive and boring, but the reward comes in finding a critical piece of evidence investigators can use to solve the crime.

Explore the Fascinating Field of Forensic Science
Forensic biologists are scientists. Most graduate from a four-year college with a degree in biology, biochemistry, molecular biology or forensic biology. They need extensive laboratory experience and may take courses in genetics, biostatistics and general and organic chemistry. They also must be knowledgeable in physics and math. Be sure any program you choose is accredited by the Forensic Science Education Programs Accreditation Commission (FEPAC).
A master's degree in forensic science is usually required in order to advance as a forensic biologist in a crime laboratory.
A successful forensic biologist must have a strong commitment to the highest standards of scientific procedure. Forensic biology is painstaking work that demands patience and attention to detail.
