The focus of my primary research field is the detailed analysis of the language used by participants in police interviews. I use tools developed for empirical and replicable studies of interaction to identify the impact of different questioning strategies in interviews with suspects and witnesses. More broadly, I provide training and professional development to legal and law enforcement professionals in cross-cultural communication, using an interpreter, and credibility assessment. I am concerned with detainees' human rights and effective interviewing within an ethical framework of practice. A more recent area of research has been the implications of widespread criminal records checking by employees for ex-offenders and for their reintegration and rehabilitation.
I am also a forensic linguist and provide linguistic expert evidence in court cases.
