Forensic Linguistics is the application of linguistics to forensic problems. One of these problems is the analysis of anonymous documents to determine their authorship, such as in cases of texts that happen to become evidence in court cases. With the increase in use of the internet in modern times, more and more crimes are committed online, for example on the dark web, where the clues left by the perpetrators are predominantly linguistic. My research is focused on quantifying and understanding individuality in language and on applying this knowledge to help the delivery of justice in cases involving disputed documents. My research is applied regularly to either help law enforcement to investigate serious crimes or is presented as evidence in court.
