Freelance Regulatory Toxicologist (chemical and pharmaceutical)

Profile Summary

I have over 30 years professional experience in regulatory toxicology in the chemical and pharmaceutical Industries and in a Regulatory Agency (Health Canada). I am a Eurotox Registered Toxicologist (ERT) and a member of the Society of Toxicology, and Beltox. I obtained a PhD in toxicology from the University of Saskatchewan (Canada) and MSc and BSc (Hons) in Biology from Carleton University (Canada). The major aspects of my freelance activities include: Serve as the principal scientific contact for contracted toxicity studies, liaise with Study Directors and Scientific staff at testing laboratories, review study protocols, monitor study progress, and assess the regulatory significance of results, including reproductive and developmental (OECD 414, 421, 443), repeat dose toxicity (OECD 408, 422) and genotoxicity studies; Maintain a thorough understanding of the toxicology requirements under the EU REACH regulations and ensure they are addressed proactively; Prepare/collate toxicological data and correspondence for regulatory submission; Conduct literature searches and critically evaluate toxicological data for products or raw materials of interest to clients; Provide expert advice in toxicology, hazard classification, risk assessment and product safety; Liaise with toxicologists, chemists, product stewards and industrial hygienists in chemical companies, regulatory agencies, industry associations, or international organisations with responsibility in toxicology, hazard communication or product stewardship; and Represent clients at meetings with Regulatory Agencies or at consortia/client meetings Prior to becoming a freelance toxicology consultant, I was Director of Nonclinical Toxicology & Pharmacology at GSK Vaccines, where I was responsible for the preparation and review of the non-clinical toxicology sections of regulatory submissions, interactions with regulatory agencies worldwide, planning and review of GLP toxicity studies, and participation in internal safety monitoring boards and project teams. I was also involved in leading and participating in technical projects at EU and US industry associations. Before joining GSK I worked for GE Advanced Materials and Huntsman Europe in senior regulatory toxicology and product safety roles that provided me with experience in chemical health hazard and risk assessment, industry association activities related to toxicology and product safety, occupational toxicology, hazard communication and hazard classification. Prior to moving to Belgium in 2000, I worked for Health Canada as a toxicologist involved in chemical, pesticide and hazardous waste management programmes. I have been an active member of the WEEL (OARS/TERA) occupational exposure committee since 1994.
