I have given expert evidence on behalf of the prosecution, the defence, and the court. I have provided reports and given evidence in the Family Court, District Court, High Court and Appeal Courts of New Zealand on a range of legal matters, including fitness to stand trial, New Zealand Bill of Rights, insanity, infanticide, sentencing matters, such as risk assessment for violent and sexual offenders, and other civil matters (Limitation Act, Immigration, employment, competency, ACC, Impairment Assessment, etc). I have provided independent parole board reports on both a private capacity and for the public system. In addition, I have given evidence in the Mental Health Review Tribunal on psychiatric matters. I would estimate that I write in total over a 200 reports on such medico-legal matters each year.
I have been trained in Root Cause Analysis. I have supervised a range of professionals in matters of psychiatry.
I have published research on the New Zealand Mental Health Act, infanticide and child homicide in New Zealand.
