What's Forensic Science?

Forensic Science is the application of science to law, carried out through the collection, preservation and analysis of evidence.

The subject area covers a large number of sub-disciplines such as forensic chemistry, forensic accounting and forensic linguistics. There's a lot of variation in course content, as it involves examining many different types of evidence such as physical evidence, numerical evidence and audible evidence.

Why study Forensic Science?

A Forensic Science degree teaches you a series of skills specific to the subject, such as how to collect a number of different types of evidence and how to preserve and analyse them.

Given the subject's focus on the law, you're also likely to gain experience in giving evidence in court. This could prove very useful if you choose to pursue a career in law enforcement.
