Dr. Morris-Schaffer is a toxicologist whose work involves evaluating potential health effects associated with pesticides, medical devices, pharmaceutical impurities, and environmental agents. He has conducted toxicology evaluations of conventional pesticides and biopesticides, including assisting clients with regulatory strategies for scientific waiver rationales, addressing data gaps, coordinating product toxicology testing and weight of evidence risk analyses.
Dr. Morris-Schaffer has prepared and reviewed medical device biocompatibility toxicology assessments under the ISO 10993 and ISO 18562 standards. He has developed Chemistry, Manufacturing and Control toxicology monographs compliant with International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidance that derive tenable permissible daily exposure levels for pharmaceutical residual impurities. He has also provided guidance for human health claim substantiation and occupational exposure levels including support for product labels, use directions, and Safety Data Sheets.
His research background is inhalation of ultrafine (nano) particles and their potential effects on developmental neurotoxicity, and he has provided technical guidance to clients on respiratory and neurotoxicity toxicological outcomes of environmental chemicals.
Dr. Morris-Schaffer has working familiarity with human health data registration for the California Department of Pesticide Regulation, United States Environmental Protection Agency, and the European Union. He has experience gathering and interpreting technical data and information for toxicology and exposure assessments under California Proposition 65, as well as developing tools to maintain sustainable Proposition 65 compliance programs. Dr Morris-Schaffer has conducted chemical and product reviews and coordinated product testing for consumer products to support compliance assessments. He is familiar with deriving estimated Safe Harbor Levels (MADLs, NSRLs), using established regulatory guidance and best practice scientific principles.
Dr. Morris-Schaffer also specializes in evaluating dermal sensitization risk from organic and/or metal residuals that can potentially leach from consumer products. He has leveraged product composition and leaching data, read-across analyses, and established regulatory approaches to provide quantitative and qualitative sensitization risk assessments for clients.
