Keynote speakers

ISEAC-41 will host a broad range of keynote presentations given by world-renowned experts from the various disciplines covered in the Scientific Program.

Confirmed speakers:

Charlotta Turner (Lund University)

Charlotta Turner is a Professor in Analytical Chemistry at Lund University in Sweden. Her research is interdisciplinary, including analytical chemistry, supercritical fluid technology, and sustainable development aspects. She has more than 20 years of experience in the fundamentals of supercritical fluids in separation processes. Her current research focus is on the development of fast, selective, and bias-free separation methods using sub- and supercritical green solvents. An important inspiration is the enhanced use of biomass and industrial byproducts as sources of high-value compounds for use in food and other industrial applications. Another of her major research topics is targeted and non-target analysis of environmental pollutants. Charlotta Turner has published over 100 scientific articles, review papers and book chapters (ORCID). She has received the Swedish King Carl XVI Gustaf’s award for environmental science (2005), the SSF Ingvar Carlsson Award for returning postdocs (2006), the AOCS Herbert J. Dutton Award for her work on lipid analysis (2015) and the Svante Arrhenius Award for her work on green and sustainable chemistry (2017).

Hans Peter Arp (NGI/NTNU)

Hans Peter H. Arp is an Expert Advisor at the Norwegian Geotechnical Institute (NGI), Oslo and a Professor in the Department of Chemistry at the Norwegian University of Science and Technology (NTNU), Trondheim. His research is focussed on both fundamental and applied aspects related to the fate, behaviour and transport of hazardous chemicals and plastic in the environment. Many of his current research focusses towards safe and sustainable recycling of sludge, water, plastics and e-waste containing hazardous substances. His current research projects include ZeroPM – zero pollution of persistent and mobile substances through prevention, prioritization and removal strategies, and SLUDGEFFECT on identifying best practices for using thermal treatments to manage hazardous substances in sludge and e-waste plastic in the circular economy.


Deputy Director of the LABERCA research unit (UMR 1329 INRAe/Oniris) in Nantes, France. PhD in food science (2001) and habilitation (HDR) to supervise research in public health (2009). Scientific leader in research related to chemical food safety from a risk assessment perspective, via the implementation of targeted and non-targeted mass spectrometry strategies, including metabolomics. Author of >140 publications, h-index 33 (ORCID). Euroresidue Award (2012). Academic lecturer at the University of Nantes (France), regular lecturer at SARAF (School for Advanced Residue Analysis) and VLAG (Wageningen University, NL). Member of institutional (Oniris) or international scientific boards (Euroresidue, NL; International Food and Water Research Center, Singapore; ACFAS, Canada; ISEAC, NL). Pilot of the international commission of the Biology and Health Doctoral School (Pays de la Loire, France).

Juliane Hollender (EAWAG)

Prof. Dr. Juliane Hollender is group leader at the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and adjunct professor at the ETH Zurich in the department Environmental Systems Science. After a master in chemistry and a PhD in environmental engineering, she worked for 10 years at the RWTH Aachen, Germany before she moved to Switzerland in 2005. Her research concentrates on the fate of emerging contaminants in the natural and engineered aquatic environment using high-resolution mass spectrometry as an important methodological tool. She is especially interested in the biological transformation of contaminants, bioaccumulation in aquatic organisms as well as non-target analysis to get a more comprehensive picture of contamination. She has been a highly cited scientist (2019-21, Clarivate) with more than 200 publications (h-index 79, google scholar, ORCID) and is a member of the steering committee of the NORMAN network.

Beate Escher (UFZ)

Beate Escher is internationally recognized for her work on chemical pollution in the environment. She pioneered the field of water quality assessment by addressing complex mixtures of chemical pollutants using in vitro bioassays. Beate Escher obtained her PhD from the Swiss Federal Institute of Technology ETH, Zürich, Switzerland and is head of the Department of Cell Toxicology at the Helmholtz Centre for Environmental Research in Leipzig, Germany, and professor at the Eberhard Karls University Tübingen, Germany. Escher’s research focuses on developing scientifically sound assessment tools and methodologies for risk assessment of mixtures of chemicals in the environment and in people. She is working on unbiased extraction methods to capture the entire exposome with chemical analytical and effect-based tools. Another research area are high-throughput in vitro bioassays and quantitative in vitro to in vivo extrapolation (QIVIVE) for risk assessment of chemicals.

Katerina Mastovska (AOAC INTERNATIONAL)

Dr. Katerina (Kate) Mastovska is Deputy Executive Director and Chief Science Officer at AOAC INTERNATIONAL, where she is responsible for leadership of all science programs and projects. She joined the AOAC staff in January 2023 but has been a very active member of AOAC INTERNATIONAL since 2004. Kate is a Fellow of AOAC INTERNATIONAL and received the Association’s highest scientific honor, the Harvey W. Wiley Award, in 2021. Prior to joining AOAC, she worked at Eurofins Scientific and has most recently served as Chief Scientific Officer at Eurofins US Food Division. Kate has been actively involved in the analysis of chemical residues, contaminants and adulterants in food for more than 25 years and has more than 70 publications in that area. She holds a Ph.D. in Food Chemistry and Analysis from the University of Chemistry and Technology in Prague.

Bart Koelmans (Wageningen University)

Bart Koelmans is an environmental chemist and ecotoxicologist by training who heads the Aquatic Ecology and Water Quality Department at Wageningen University. In the field of plastic research, his group aims to bridge the gap between conceptual and empirical approaches to obtain a mechanistic understanding of the risks of microplastic for human health and the environment. For microplastics, his risk assessment framework was the first to be applied in a regulatory setting. Bart is a global highly cited researcher (Clarivate Analytics), advises international organizations like the World Health Organization and the UN, led high-profile international working groups on the risks of plastic pollution, such as the European Commission’s Science Advice for Policy by European Academies (SAPEA) expert group on Microplastics in Nature and Society, and is Editor-in-Chief of the journal Microplastics and Nanoplastics.

Marijn Korndewal (OECD)

Marijn Korndewal is a Policy Analyst at the Environment Directorate of the Organisation for Economic Co-operation and Development (OECD). She leads the OECD’s work on water quality and health. The OECD’s programme on water quality currently focuses on monitoring methods and policy instruments that minimise the risk of contaminants of emerging concern in freshwater, such as pharmaceutical residues and endocrine disruptors. Before joining the OECD, Marijn worked on water resources management at river basin authorities and the United Nations Environment Programme. Marijn holds an MSc in Water Science, Policy and Management from the University of Oxford.

Bruno Dujardin (EFSA)

Bruno Dujardin is a senior scientific officer at the European Food Safety Authority (EFSA), where he has gained extensive experience in the regulatory risk assessment of chemicals. Throughout his career, Bruno has been responsible for dietary exposure assessment in different domains of EFSA (e.g. pesticides, feed additives, etc.) and has contributed to new methodological developments in this area. Recently, he took up a new role as team leader within the Methodology and Scientific Support unit. His team provides transversal support on exposure assessment, statistical data analysis and modelling. Within this capacity, Bruno is also responsible for steering the implementation of more holistic approaches that account for combined exposure to multiple chemicals. Before joining EFSA in 2007, Bruno gained his first professional experience at the Federal Public Service for Public Health, Food Chain Safety and Environment in Belgium.
