Dr. Thiffault joined Exponent in December 2022 and brings with her over 20 years of experience in the chemical & pharmaceutical industries. Dr. Thiffault has an in-depth understanding of chemical regulation and a broad toxicological expertise focusing on food contact substances, medical devices, pesticides, consumer goods and cosmetics to support compliance/registration in North America, Europe and China.

Dr. Thiffault focuses her work at Exponent supporting food contact materials, cosmetics, medical devices and consumer products.

Dr. Thiffault has provided an expert opinion to our clients on food contact materials and cometics to ensure safety and regulatory requirements were met.

Dr. Thiffault is a member of the American Board of Toxicology and holds a DABT. She is also an accredited member of the European Registered Toxicologist and a Project Management Professional.

For the last 20 years, Dr. Thiffault has held key positions including Senior Director of Product Stewardship where she implemented a medical device safety testing program. At Edgewell, she held the position of Senior Principal Scientist where she evaluated the safety of Over the Counter (OTC) drugs and cosmetics by applying risk assessment principles. She also ranked-prioritized novel ingredients for development using read-across and risk assessment tools (qSAR, Read-Across, TTC, ToxTree, and EpiSuite).

As Director of Product Stewardship at Advansix, Dr. Thiffault built the regulatory function to support innovation for solvents and food contact materials and implemented processes to ensure regulatory compliance across businesses. She provided predictive environmental and mammalian toxicology modeling (qSAR) to support R&D to identify chemicals with optimal toxicity profiles for development.

Prior to Advansix, she joined Henkel as Director of Toxicology and provided human risk assessments (TRA, LHAMA certification) using modeling tools (ConsExpo, BMD, and OECD toolbox software) to support product safety and proof of concept clinical trials for use of adhesives in medical devices, consumer products, and in direct/indirect food contact material (e.g., packaging). She collaborated with CROs to conduct animal toxicity studies and interfaced with R&D to advance chemistry with optimal toxicity profiles.

At FMC, Dr. Thiffault provided global toxicology expertise to support the registration of pesticides worldwide. She drove strategy to support pesticide registration and oversaw GLP and non-GLP toxicology studies from acute to chronic toxicology, as well as PK studies in various animal species in accordance with OPPTS/OCSPP and OECD guidelines.

Dr. Thiffault received a BS in Chemistry and a PhD in Pharmacology from McGill University while in the laboratory of Dr. Rémi Quirion, where she studied the role of oxidative stress in the MPTP mouse model of Parkinson's disease. She continued her training as a post-doctoral fellow on the role of pesticides in the etiology of Parkinson's Disease at the Parkinson's Institute in Sunnyvale CA and on mitochondrial physiology at the Center for Neurodegenerative Diseases at the University of Virginia. Her work has been published in more than 25 peer-reviewed publications.
