In Forensic Linguistics we analyse the language of crime, including 

identifying authorship, interpreting meaning and assessing threat. I 

work on documents such as suicide notes, ransom demands, threat 

texts, phone texts from missing persons, terrorist threats, fraudulent 

insurance claims, malicious and hate mail, threatening phone calls 

and hoax phone calls, and police interviews (recorded or written).

I have assisted investigators and lawyers, as well as corporate and 

private clients across the world in over 400 cases including: 

homicide, kidnap, acts of terrorism, insurance fraud, assault, victim 

abuse, narcotics distribution and people trafficking.
