Forensic Scientist


    Forensic scientists use analytical and scientific techniques to examine evidence from crimes and prepare legal statements that summarize the results for court cases.

    As a forensic scientist you’ll provide impartial scientific evidence for use in courts of law to support the prosecution or defence in criminal and civil investigations.

    You’ll be primarily concerned with searching for and examining contact trace material associated with crimes. This material can include:

    • blood and other body fluids
    • hairs
    • fibres from clothing
    • paint and glass fragments
    • tyre marks
    • flammable substances used to start fires.

    The work usually involves:

    • chemistry – the examination of substances such as paint or chemicals, including fire investigation and accident reconstruction
    • biology – DNA testing and the examination of minute contact traces, such as blood, hair and clothing fibres
    • drugs and toxicology – testing for restricted drugs, examining tissue specimens for poison detection, and the analysis of blood and urine samples for alcohol, for example in drink driving offences.

    To become a forensic scientist, a degree in forensic science or another science subject is necessary. Postgraduate study in forensic science is often required, especially after studying a general science subject at undergraduate level.

    Degree subjects such as statistics and geology can be useful for entry into specialist areas of forensic science.
