Sophie Kaszuba, BSc (Hons) is a Consultant Toxicologist specialising in reproductive and developmental toxicology, with additional expertise in genetic toxicology.
Sophie is currently a consultant within the Human Safety Team at Blue Frog Scientific, where she supports clients across the chemical sector. Her work includes toxicology study monitoring, comprehensive literature reviews using the Klimisch scoring system, data interpretation, weight-of-evidence assessments, data gap analysis, testing strategy development, and preparation of IUCLID technical dossiers to meet regulatory submission deadlines.
Prior to joining Blue Frog Scientific, Sophie spent five years at Charles River Edinburgh (contract research laboratory), progressing from Assistant Scientist to Study Director. In this role, Sophie directed GLP-compliant developmental and reproductive toxicology (DART) studies to meet global regulatory requirements. She led multidisciplinary teams in the design and execution of complex studies, including the OECD 443 Extended One Generation Reproductive Toxicity Study and the EPA Comparative Thyroid Assay, ensuring scientific integrity, regulatory compliance, and delivery to client expectations. Sophie was also responsible for interpreting study data and producing final reports for regulatory submission.
Alongside her technical leadership, Sophie served as a Trainer for new Study Directors, mentoring colleagues on study design across pharmaceutical, chemical, and agrochemical programmes, as well as the principles of Good Laboratory Practice (GLP). She supported the development of new study directors within the organisation, strengthening both technical capability and client communication standards.
