Forensic Scientist (Physical & Chemical)
This role is ideal for individuals with a strong passion for chemistry, physics, and meticulous analytical work. It offers the chance to delve into the microscopic world of trace evidence, using advanced scientific instruments to uncover crucial facts that can solve crimes. While demanding in terms of precision and technical skill, the satisfaction of contributing to justice through objective scientific analysis is deeply rewarding.”
About This Role
Analyzing physical trace evidence and chemical residues using scientific techniques for legal cases.
A Day in the Life
A Forensic Scientist (Physical & Chemical) spends their day in the lab, meticulously analyzing non-biological evidence from crime scenes. This involves using a range of scientific techniques and instruments to identify and compare trace evidence like fibers, paint, glass, soil, and chemical residues, preparing detailed reports, and providing expert testimony.
- Receive, document, and manage physical and chemical evidence samples
- Analyze trace evidence (e.g., fibers, paint, glass, soil, gunshot residue) using microscopy and spectroscopy
- Conduct chemical analysis of unknown substances, drugs, and explosives
- Operate and maintain advanced analytical instruments (e.g., GC-MS, FTIR, SEM-EDS)
- Interpret complex analytical data and compare findings to reference databases
- Maintain strict chain of custody and quality control standards
- Prepare comprehensive scientific reports for law enforcement and legal proceedings
- Provide expert testimony in court regarding physical and chemical evidence
Work Environment
A controlled laboratory environment, often involving the use of hazardous chemicals and specialized analytical equipment. Requires strict adherence to safety protocols, precision, and meticulous documentation.
Typical hours: 45h/week · WLB score 7/10 · OCCASIONAL overtime
Generally predictable hours, but urgent cases or court appearances can require occasional overtime. The work can be intellectually demanding but less emotionally taxing than biological evidence.
