Giel Hendriks has a PhD in molecular cell biology from Utrecht University and worked for four years as a post-doctoral fellow at Leiden University, studying the relationship between DNA damage and gene mutations. After this he moved to the Leiden University Medical Center to develop in vitro reporter systems to understand the mechanisms of genotoxicity. Currently, he is the CEO of Toxys, a contract research organisation (CRO) he started in 2014. During the past years, Toxys has developed various in vitro assays to ensure the safety of novel medicines, chemicals and consumer products without the use of animals.

Carsten Kneuer is a Toxicologist and the Head of the Unit “Toxicology of Active Substances and their Metabolites“ in the Pesticides Safety Department of the German Federal Institute for Risk Assessment. His group is evaluating the mammalian toxicology of pesticides within the EU assessment framework and actively involved in various projects aimed at the advancement of our risk assessment practice.

Maricel has been working at Nestlé since 2002, with key scientific contributions in the safety-by-design area bringing in vitro solutions to food quality and safety challenges for prioritization and decision-making. Involved in the packaging safety area since 2010 with the application of multidisciplinary tools to assess the safety of new packaging material using qualified in vitro tools. External collaborations with academia and industry on various food safety issues.

Krista Meurer has been a Regulatory Toxicologist for Crop Protection at BASF since 2008. In support of European and global registrations, she is responsible for human health risk assessment for pesticide products and active substances. Based on 10 years experience as a Study Director in contract research, Krista has a special interest in genetic toxicology testing and is a member of the CropLife Europe genotoxicity expert group as well as the Health and Environmental Sciences Institute (HESI) Genetic Technical Committee (GTTC).

Juan Parra Morte has been Toxicologist in the Pesticide Peer Review Unit of EFSA since 2008. He has been actively involved in the assessment of pesticide active substances, their metabolites and impurities, including the EFSA PPR, the OECD Guidance on Residue Definition and EFSA's outsourced projects on the Genotoxicity Database and QSAR and Read-Across for the genotoxicity of metabolites. He has also been involved in supporting the EFSA Working Group on Genotoxicity, being a co-author of the EFSA Scientific Committee Guidance and Statements regarding genotoxicity since 2017.

Benjamin Sachse is a European Registered Toxicologist and has been working as a Scientific Officer in the Food Safety Department at the German Federal Institute for Risk Assessment (BfR) since 2016. He is responsible for the risk assessment of botanical ingredients in foods and has a background in genotoxicity assessment for several years.

Olga Tcheremenskaia is a Senior Researcher at Environment and Health Department of the Italian National Institute of Health (ISS) and has worked at this Institute since 2001. She has coordinated several projects funded by EFSA and ECHA, as well as co-coordinating the OECD (Q)SAR Assessment Framework working group. Her current activities include serving as the Italian representative in several OECD expert groups, including the OECD IATA case studies project, the OECD QSAR Toolbox Management Group, and the OECD Emerging Science in Chemicals Assessment (ESCA) expert group. She participates actively in the EU_PARC project and coordinates the Task on improving existing computational methodologies within the EU_WILDPOSH project and the EFSA project on updating the EFSA genotoxicity database. A major part of her research focuses on chemical risk assessment using animal-free methods, particularly New Approach Methodologies (NAM) based on in silico approaches such as (Q)SAR models, read-across, and AOPs. She also has extensive experience managing toxicological data and developing relational databases.

Frans Verstraete works in the European Commission in the Directorate General for Health and Food Safety (DG SANTE) and is responsible for legislation on contaminants.

Paul A. White obtained his BSc in microbiology and immunology, and PhD in environmental toxicology, from McGill University in Montreal. He conducted post-doctoral research at US EPA facilities in Rhode Island and North Carolina; investigating the mutagenic hazards of municipal wastewaters. He joined Health Canada in 1999 and is currently a senior research scientist in the Environmental Health Science and Research Bureau. In 2002 he was appointed Professor of Chemical and Environmental Toxicology in the Department of Biology at the University of Ottawa. His current work investigates the mutagenic and carcinogenic hazards of complex mixtures, the design and validation of in vitro tools for genetic toxicity assessment, the use of molecular biomarkers for mutagen exposure assessment, and the application of quantitative methods for interpretation of genetic toxicity dose-response data. He has published over 125 peer-reviewed papers, and his work has been cited over 6700 times. He currently serves on the editorial boards of Environmental and Molecular Mutagenesis, Mutation Research Reviews, Genes and Environment, and Food and Chemical Toxicology, and he is currently the vice-president of the International Association of Environmental Mutagenesis and Genomics Societies (IAEMGS).
