A Career in Forensic Science: Student Questions Answered

For many students, an interest in forensic science begins with the cases they see in TV dramas, documentaries or films. But the reality of forensic casework is often more complex, more detailed and more varied than it appears on screen.

At Forensic Access, we are often contacted by students who are keen to understand what a career in forensic science really involves, from the skills and qualifications required to the realities of day-to-day casework.

Recently, Caroline Crawford, Forensic Scientist: Biology at Forensic Access, spoke with a student who was considering her next steps after college, including university options and future career paths. Their discussion has been adapted into a short Q&A to share Caroline’s insight with other aspiring forensic scientists.

Caroline has over 25 years’ experience as a forensic scientist and has been part of the Forensic Access team since 2009. Specialising in forensic biology, she examines and interprets biological evidence, with expertise in DNA, body fluid evidence and blood pattern analysis.

Throughout her career, Caroline has worked on a wide range of complex cases, presented evidence in court as an expert witness and delivered specialist training in areas including blood and DNA evidence.

If you’re considering a future in forensic science, Caroline’s answers offer a useful insight into some of the questions you may be asking.

What does a forensic scientist actually do?

Caroline explained that one common misconception is that forensic scientists spend most of their time attending crime scenes. In practice, much of the work takes place in the laboratory and through detailed case review.

Forensic scientists examine exhibits, analyse results, interpret findings and prepare clear, impartial reports for the court. In some cases, they may also be required to give evidence as an expert witness.

What does a typical day look like for a forensic scientist?

Caroline discussed that many people don’t realise that there are different types of roles within forensic science, and the day-to-day work can vary significantly depending on the role.

An examining scientist will usually spend more time working practically in the laboratory. This can include examining items, carrying out tests for different body fluids, recovering potential DNA evidence, photographing findings and carefully documenting their work.

A reporting scientist has a different role. At the start of a case, they review the information provided by the police or legal teams, consider the circumstances and decide which forensic examinations may help answer the questions being asked. Once the laboratory work has been completed, they interpret the findings, consider what the results mean in the context of the case and prepare expert reports to support the investigation or court process.

Some forensic science roles are very specialised, focusing on one particular part of the process, while others involve looking at the wider case. If you’re considering a career in forensic science, it’s important to understand what each role involves and what opportunities there may be to develop your skills and progress.

Both examining and reporting scientists play an important role in forensic casework, combining practical science with careful interpretation to help answer important questions within an investigation.

What are the most rewarding and challenging parts of the role?

One of the most rewarding aspects of the role is knowing that forensic science can help the court make informed decisions. This can involve bringing together different pieces of evidence, interpreting scientific findings and helping the court understand what those results may mean in the context of a case.

For Caroline, some of the most rewarding cases are not necessarily the highest-profile ones, but those that are scientifically challenging. Complex cases often require forensic scientists to carefully consider different findings, evaluate the evidence and help answer important questions about what may have happened.

The role can also be challenging. Forensic scientists must work with precision, often within strict timescales and against the backdrop of wider pressures across the criminal justice system. Caroline also noted that public expectations of forensic science are often shaped by television, which can differ significantly from the realities of forensic casework.

What skills are important for a forensic scientist?

Forensic science requires more than technical knowledge. Attention to detail, methodical working, critical thinking and clear communication are all essential in the role of a forensic scientist.

Scientists must be able to explain complex findings in a way that can be understood by non-scientists, including legal teams, juries and the court. The ability to remain calm and objective under scrutiny is also important, particularly when giving evidence.

What advice would you give to aspiring forensic scientists?

Caroline encourages students who are considering a job in forensic science, must first build a strong foundation and knowledge in science. Degrees in subjects such as biology or chemistry can provide flexibility and help keep future career options open.

She also emphasised the importance of choosing a subject you enjoy, as genuine interest and commitment are important throughout both study and professional practice. Gaining laboratory experience, whether through university, research or related opportunities, can also be valuable preparation for a career in forensic science.

Supporting future forensic scientists

We are grateful to Caroline for sharing her time and expertise. We hope this Q&A provides useful insight for students considering a future in forensic science and helps clarify what the role can involve beyond common perceptions of the profession.

While we are unable to offer work experience placements, we are committed to supporting the next generation of future scientists where we can. Our forensic scientists regularly share their knowledge through educational sessions and guest lectures, to help students understand how forensic science is applied in real investigations and within the criminal justice system.

Guest lectures can be tailored to support students’ understanding of forensic science in practice, from how evidence is examined and interpreted to the role of the forensic scientist within the criminal justice system. Sessions can also provide insight into real casework, expert witness work and how scientific findings are presented in court.

If you are a student or educator and would like to learn more about careers in forensic science, or discuss guest lecture opportunities with Forensic Access, please contact our training team at training@forensic-access.co.uk.
