Cathryn Tonne
Research Professor; Climate, Air Pollution, Nature and Urban Health; Barcelona Institute for Global Health (ISGlobal), Spain

Keynote 1: Climate action as a driver of healthier exposomes

Cathryn Tonne is an environmental epidemiologist focusing on the health effects of air pollution from outdoor and household sources and their intersection with sustainable development. Her research has investigated exposure patterns and health effects of air pollution in high- as well as low- and middle-income countries.

One of her main research interests is in the health co-benefits of climate change mitigation. She is co-director of the Lancet Countdown for Health and Climate Change in Europe and leads the working group focused on mitigation actions and health co-benefits.

Jonathan Martin
Professor and Unit Head of Exposure and Effects Unit (ACESx), Department of Environmental Science, Stockholm University, Sweden

Keynote 2: From Sample to Molecules to Meaning: High-Resolution Chemical Exposomics for Precision Health

Professor and Unit Head of the Exposure and Effects Unit (ACESx), Department of Environmental Science, Stockholm University, Sweden. He is also Scientific Director of the National Facility for Exposomics, Metabolomics and Exposomics Platform, SciLifeLab, Sweden. Jonathan Martin's research focuses on the chemical exposome, and specifically on the development of methods to measure it in health and exposure studies. His research group develops new methods for environmental sampling and sample preparation, and combines these with combined target/nontarget high-resolution mass spectrometry (HRMS) workflows to discover the complex mixture of small molecules in our bodies and in the environment around us.

Jinhee Choi
Professor of Environmental Toxicology, University of Seoul, South Korea

Keynote 3: Integrating Consumer Product-Based Exposure with AOP-Anchored AI-Based Toxicity Prediction for Exposome-Informed Chemical Prioritization

Dr. Jinhee Choi is Professor of Environmental Engineering at the University of Seoul and Director of the Chemical Big Data Science AI Research Center. Her research bridges ecotoxicology, human toxicology, and computational toxicology, integrating mechanistic toxicology and data science to advance New Approach Methodologies (NAMs) and Next-Generation Risk Assessment (NGRA) under a One Health framework. She has developed AOP-informed and explainable AI approaches for toxicity prediction, chemical mixture risk assessment, and regulatory applications in consumer product and environmental safety. A former President of the Korean Society of Environmental Toxicology and Health and advisor to the Korean Presidential Advisory Council on Science and Technology, she was recognized as a Highly Cited Researcher in Toxicology (2015–2017). Her work emphasizes transparency, interpretability, and the integration of human and environmental health in modern chemical safety assessment.

Kees de Hoogh
Researcher, Institute for Risk Assessment Sciences (IRAS), Utrecht University, Netherlands

Keynote 4: Advances in Spatiotemporal Modelling for External Exposome Assessment

His scientific research focuses on spatial modelling and exposure assessment for studies on environment and health. His recent focus involves cutting edge fine resolution spatio-temporal modelling to derive refined exposures using satellite and ancillary data. He has been involved in a number of large projects (BioSHARE, ESCAPE, ELAPSE) where he co-led the air pollution exposure assessment, and currently is a co-PI of the European research project EXPANSE, the NWO Gravitation programme Exposome-NL, the Utrecht Exposome Hub and PI of MOBI-AIR studies.

Joaquin Migeot
Neuroscientist, Latin American Brain Health Institute (BrainLat), Universidad Adolfo Ibañez, Chile. Global Brain Health Institute (GBHI), Trinity College Dublin, Ireland

Keynote 5: Unequal exposomes shaping global brain health

Joaquín Migeot is a researcher at the Latin American Brain Health Institute (BrainLat), Universidad Adolfo Ibáñez, where he leads research at the intersection of social determinants of health, cognitive aging, and equity in brain health across Latin America. He is also an Global Brain Health Institute (GBHI) Atlantic Fellow for Equity in Brain Health. He has authored over 25 peer-reviewed publications in leading international journals, including Nature Medicine, Nature Communications, Nature Aging, Trends in Neurosciences, and Alzheimer’s & Dementia. His work integrates social determinants of health, exposome science, and neurobiological markers to understand how structural inequality and lived environments shape brain aging and dementia risk. He contributes to large-scale regional collaborations, including the ReDLat Consortium, where he collaborates in the integration and analysis of social, clinical, cognitive, and neuroimaging datasets across multiple Latin American countries.

Tanya Alderete
Associate Professor, Bloomberg School of Public Health, Johns Hopkins University, USA

Keynote 6: From Exposures to Outcomes: A Multi-Omics Window into the Infant Gut Microbiome

Dr. Tanya Alderete's current research is centered on the intersection of environmental exposures, metabolic health, and the human microbiome, with a focus on obesity and type 2 diabetes. Dr. Alderete employs a multidisciplinary approach, integrating clinical research, epidemiological methods, and omics techniques to explore how environmental factors contribute to chronic diseases.
