BSc(Ed), BSc(Hons), MSc(Chem), MSc(Appl Tox), LLB, MPhil(Med Law), PhD(Med Law), PhD(Chem).

As a Director, Forensic Toxicologist, Expert Witness, Author, and Educator, my career is a testament to a multidisciplinary approach, combining extensive experience with a robust academic background.  Following obtaining degrees in Chemistry and advanced studies in Toxicology, I further honed my expertise with a focus on Medical Law & Ethics. My diverse education and wealth of experience underscores my commitment to merging science with legal and ethical principles, particularly in forensic toxicology.

In my current role as Scientific and Laboratory Director at Expert Laboratory Services, I’ve led and performed forensic analyses, provided expert court testimony, developed drug and alcohol testing policies and consulted on substance abuse testing for the industry and private individuals.

In essence, my work embodies a commitment to scientific excellence, ethical practice, and the enhancement of forensic toxicology’s role in serving justice and public safety. This comprehensive approach not only advances the field but also ensures the integrity and reliability of forensic evidence in legal contexts.
