Peter Maskell started his career as a Pharmacologist graduating with BSs (Hons) in Pharmacology from the University of Portsmouth in 1996. Following graduation he worked at Wyeth Laboratories as Quality Control Analyst until starting a PhD investigating GABAA receptors at Oxford Brookes University in 1997. He was awarded his PhD in 2001. This was followed by postdoctoral research as a KTP associate at Oxford Brookes University (in collaboration with Vernalis) and the University of Birmingham.
In 2005 he was appointed as a Pharmacology Teaching Fellow at the University of Bristol. In 2009 he became a Lecturer in Forensic Toxicology/ Reporting Forensic Toxicologist at the University of Dundee. As part of his remit he was responsible for quality management of the forensic toxicology laboratory that provided analysis of various post-mortem samples for the Central, Tayside and Fife regions of Scotland under contract from the Scottish Crown Office for unexplained death cases. In 2013 Dr Peter Maskell moved to the University of Huddersfield to take up the position of Senior Lecturer in Forensic Toxicology. In 2017 he moved to Abertay University in Dundee. His research is focussed on uncertainty of measurement (particularly in alcohol calculations), post-mortem drug redistribution, novel psychoactive substances and interpretation in forensic toxicology.

After a career break to bring up her family, Susannah returned to the field of Analytical Science by taking up the position of Analytical Chemist at RPS Group in Bedfordshire. Working across GC-MS and LC-MS sections she now specialising in the analysis of water, river water, soil, sediments and crops for pesticides and environmental contaminants.
Over the years Susannah's main area of practice has been the toxicological analysis of biological samples submitted on behalf of coroners, police, clinicians and other health professionals. She was involved in case reporting and interpretation of analytical results. Both ASI Ltd and RPS Group are GLP/GCP/UKAS 17025 compliant laboratories and Susannah's additional Quality roles in both companies has been prominent, ensuring compliance.
She has attended LTG (formerly London Toxicology Group) meetings since 2004 and has been the secretary for over 10 years. She has regularly presented over the years at many meetings on the subject of newly-introduced designer drugs. She has been involved in researching designer drugs in collaboration with Mr John Ramsey, TICTAC Communications at St George's, since she completed her MSc project with him in 2004. This work involved characterising tablets, capsules, liquids, and powders associated with the dance scene. She has now attended four Glastonbury Music festivals and advised Avon and Somerset police in the identification of recreational drugs on site.
Susannah has published 21 peer-reviewed original papers in leading journals (5 first author). She has also presented 18 posters at international conferences such as The International Association of Forensic Toxicologists (TIAFT) and the International Association for Therapeutic Drug Monitoring and Clinical Toxicology (IATDMCT), for which she is a member of the Young Scientists Committee.
