Dr. Sue Paterson

Sue has worked as a forensic toxicologist for over 30 years. Her career has focused on offering a service to HM Coroners. Over the years Sue has dealt with a wide variety of cases including several high profile ones both for the police and Coroners.
Her unit not only provides a routine service but is actively engaged in research. This research is focused on the problem of interpretation which is the biggest challenge in forensic toxicology. She has published 28 papers, 9 of them in the last five years, all in quality journals.
Sue acted as an assessor for CRFP from 2002 until 2009 and had taken over the role of lead assessor just before it was brought to a close. She probably carried out more assessments than anyone else; it took considerable time and energy. Sue expended the time and energy doing this because she was committed to the aims of CRFP. As an assessor for CRFP she always used the SOFT Guidelines as the standards against which she carried out her assessment. However Sue felt she should not be deciding this alone but the standards should be discussed and agreed by all concerned. It is this that initiated the collating of the guidelines which we have now all agreed.
Her experience and commitment to the profession, as demonstrated by her work for CRFP, make her a worthy candidate for a post on the UKIAFT Council.

Mr Peter Streete

Peter has worked within the field of toxicology at the Medical Toxicology Laboratories (formerly "The Poisons Unit") for over 34 years. He has progressed from an initial position as a trainee technician to his current position as lead scientist and head of Clinical & Forensic Toxicology. For the past 25 years Peter has been actively involved in the provision of Forensic Toxicology Services, primarily associated with work for Coroners. His work in the field of volatile substance analysis has allowed him to provide both analytical data and missing case data related to fatalities to the Volatile Substance Abuse (VSA) Mortality Project for many years now. Monitoring of concentrations found in overdose with non-steroidal anti-inflammatory drugs and more particularly ibuprofen, helped proved the comparative safety of the drug and was part of the reason why Ibuprofen was allowed to be sold 'over the counter'. Peter also undertook the ibuprofen determinations in a case where an uncorrectable acidosis caused by ibuprofen resulted in what may be considered as the first fatality resulting from Ibuprofen alone.
As a participant in the UKFT Forum and UKFT Network, predecessors of the UKIAFT, Peter has welcomed the opportunity to play a part in the establishment of a structure and standards for Forensic Toxicology in the future.
