How to become a forensic scientist

Strathclyde forensic student

Forensic scientists play an important role in our judicial system – bringing perpetrators to justice and righting wrongs. You’ll use a wide range of scientific skills and methods to provide evidence in a court of law and solve crimes.

What is a forensic scientist?

Forensic science is a way of using science in a court of law – both criminal and civil. You could be using your scientific skills to examine evidence from crime scenes or sharing your knowledge to testify as a key witness during a trial.

Although most of your work will be carried out in a lab, the results of your work will play an important role in our society. You could be analysing blood samples from a murder scene one day, and verifying the authenticity of a key document the next. More experienced forensic scientists will also be called to examine crime scenes themselves, making them a vital part of a criminal case.

Should I become a forensic scientist?

Forensic science is the perfect combination of the law and science. If you have a keen scientific mind with a great eye for detail, you could use your skills to help make the world a better place. To be a successful forensic scientist, you will need to be:

  • Logical: not everything is at it seems, and it will be up to you to use your expertise and see what others cannot.
  • Objective: forensic science covers many sensitives topics which you may be asked to comment on in a court of law.
  • Trustworthy: working on active cases means you have access to confidential information which can sway the result of a trial.
  • Able to concentrate: working under pressure and to a deadline are part of the job – the evidence you collect may be used within criminal trials.
  • Confident: using your knowledge and experience, you must be confident in your findings and sharing your results with the law – sometimes under cross-examination from a lawyer.

If you have these traits, you could have a great career as a forensic scientist. You’ll mostly be working in a laboratory, though occasionally at crime scenes, in court, or in an office. The work can often be long and time-consuming, but the results are important. As a forensic scientist, you are truly making a difference.

The main types of forensic science are chemistry, biology and toxicology. These areas will relate to your expertise and interests – and will affect the type of work you do. You will then use your expertise to examine bodily fluids, hairs, tyre marks, and fibres – before presenting your evidence in either a written report or as a witness in a court room.

Forensic science is a competitive industry, so further study can also help you secure employment as a forensic scientist. If your undergraduate degree is in a more general science subject, a postgraduate degree can be used to develop more specific skills in forensic science. However, if your undergraduate degree is in forensic science, a postgraduate degree can help you focus on a specific subject area as your speciality.

There are many forensic science degrees available to choose from, so it’s important to check your programme is accredited by The Chartered Society of Forensic Sciences (CSFS). The University of Strathclyde offers a degree in forensic science, which is accredited by both the CSFS and the Royal Society of Chemistry.

- Be analytical
- Be able to work well in a team
- Have strong written and spoken communication skills
- Have good colour vision.
