What it is
Forensic science applies science to criminal investigation — analyzing physical evidence like DNA, fingerprints, drugs, and trace materials to help solve crimes. It combines biology, chemistry, and criminal justice, mostly in crime laboratories.
Key note: real forensic-science jobs are science-heavy — most crime labs prefer a strong chemistry or biology background (a forensic-science BS with lab rigor, not a generalist criminal-justice degree). The TV image overstates how many field/CSI roles exist.
What you'll study
Forensic science is a lab-based natural-science major:
- Science coreGeneral & organic chemistry, biology, and often physics
- Forensic coreForensic biology/DNA, forensic chemistry, trace evidence, toxicology
- AppliedCrime-scene methods, evidence handling, courtroom testimony, and lab work
Concentrations & focus areas
- Forensic Biology / DNAGenetic evidence
- Forensic ChemistryDrugs & trace evidence
- ToxicologyPoisons & substances
- Crime-Scene InvestigationEvidence collection
- Digital ForensicsElectronic evidence

Job outlook & demand
The BLS projects forensic science technicians to grow faster than average, though it's a relatively small field with competitive lab positions. Digital forensics is a fast-growing sub-area. A strong science foundation is essential for hiring.
Pay: median, range & trajectory
Per the U.S. Bureau of Labor Statistics, forensic science technicians had a median around $67,440. Digital-forensics and toxicology specialties, and roles in high-cost states, pay more; entry lab roles vary.
Degree levels it's offered at
Offered across these levels — click a level to learn about it:
A bachelor's with strong chemistry/biology is the entry credential; a master's helps for specialized (DNA, toxicology) and advancement roles.
Is it right for you?
You might thrive here if you love science and the lab, are meticulous, and want to apply science to justice.
Reality check: forensic science is science-first — prioritize rigorous chemistry/biology coursework, not just criminal-justice content, and consider digital forensics for a fast-growing, well-paid path.
