Forensic biology is the application of biology to law enforcement. It includes the sub-disciplines of Forensic serology, Forensic botany, Forensic entomology, Forensic Microbiology, Forensic odontology, anthropology, and various DNA or protein-based techniques.

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.
