Leonardo Trasande is Professor of Paediatrics, Environmental Medicine, and Population Health at NYU Grossman School of Medicine, where he serves as Vice Chair for Research in Paediatrics and Director of the Division of Environmental Paediatrics.

A globally recognised leader in environmental health, his research focuses on the impact of chemicals on hormones and human development, and on making the economic case for policy action. He is perhaps best known for landmark studies published in Lancet Diabetes and Endocrinology documenting the disease costs of endocrine-disrupting chemicals at $340 billion annually in the US and €163 billion in Europe.

He organised the Endocrine Disrupting Chemical Disease Burden Working Group, bringing together nearly 30 international scientists to advise policymakers on the burden of chemical-linked disease. He has also served on expert panels for the American Academy of Paediatrics, the CDC, and the UN Environment Programme.

Dr. Shanna H Swan is an environmental and reproductive epidemiologist. She is Professor of Environmental Medicine and Public Health at the Icahn School of Medicine at Mount Sinai, New York, Adjunct Professor in Obstetrics and Gynaecology at the University of California, San Francisco and Senior Scientist at Environmental Health Sciences. Her work examines the impact of environmental exposures on reproductive health and neurodevelopment.

Since 1998 Dr. Swan has conducted multi-centre pregnancy cohort studies, which now include more than 1,500 mothers and their children, to better understand how prenatal and early childhood exposure to stressors can impact children's health and development. In 2017 Dr. Swan and colleagues published “Temporal Trends in Sperm Count: a systematic review and meta-regression analysis”, which was updated in 2022.

In 2021 Dr. Swan and co-author Stacey Colino published: Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Health, and Imperilling the Future of the Human Race which has been translated into nine languages. Dr. Swan is committed to broadening the impact of this science to protect the health of all segments of society and all species on the planet. 

Prof Paul Fowler is Chair in Translational Medical Sciences at the University of Aberdeen and a Fellow of the Royal Society of Biology. Having earned both his BSc (Hons) and PhD at Aberdeen, he began his career in Obstetrics & Gynaecology working on ovarian hormones before moving to the Institute of Medical Sciences in 2000, which he went on to direct from 2015 to 2021. His research elucidates mechanisms regulating human reproduction and development, with a particular focus on how endocrine-disrupting chemicals, maternal smoking, obesity, and medication use disturb foetal development. His group is one of the very few worldwide studying the normal first- and second-trimester human foetus. Prof Fowler has authored over 170 peer-reviewed publications and has led or contributed to four major EU research programmes on endocrine disruption, including the €6.1 million Horizon 2020 FREIA project.

He served on the European Food Safety Authority's Panel on Food Additives and Flavourings from 2018 to 2024, and was an expert panel member for the Endocrine Society's reports on the economic costs of endocrine-disrupting compounds.

Dr Pete Myers is Chair, founder and Chief Scientist of Environmental Health Sciences. As a co-author of Our Stolen Future, he has worked on endocrine disruption, a term he coined, since the early 1990s, publishing many research and policy papers in the peer-reviewed literature. He has chaired the board of the Science Communication Network since its founding in 2003 and also served as board chair of the H. John Heinz III Center for Science, Economics and the Environment. Dr. Myers is a trustee of the Jenifer Altman Foundation and has served as Board President of the Consultative Group on Biological Diversity, an association of 40+ foundations supporting work on biodiversity, climate, energy and environmental health. In 2020 he joined Professor Terry Collins as co-founder of Sudoc.com. 

Prof Dr Terrence J. Collins is the Teresa Heinz Professor of Green Chemistry and Director, Institute for Green Science, at Carnegie Mellon University in Pittsburgh, Pennsylvania. Terry received his degrees from the University of Auckland where he is a Distinguished Alumnus and Honorary Professor. He first learned of the insidious health damage caused by certain commercial chemicals while a student.

His multidisciplinary research, educational and entrepreneurial programs aim to provide solutions for pollutants that exhibit low dose adverse effects (lodafs). Terry is the creator-founder of the multiply awarded startup Sudoc, LLC that is commercialising TAML® applications while being a working example of what a sustainable chemical corporation should look like. 

Univ. Prof. Dr. Lukas Kenner is a distinguished medical researcher and professor specializing in pathology and oncology. He holds multiple positions, including Professor at the Department of Pathology at the Medical University of Vienna and Head of Laboratory Research at the Institute of Clinical Pathology. Additionally, he serves as a co-director at the Ludwig Boltzmann Institute for Cancer Research. Dr. Kenner's research primarily focuses on the molecular mechanisms that underpin cancer development and progression.

Since the early 2000s, he has led several major studies investigating genetic markers and their role in predicting cancer outcomes. His work has significantly contributed to the development of targeted therapies that improve the precision of cancer treatment. In 2019, Dr. Kenner co-authored "Pathways to Precision Medicine", a comprehensive review on how molecular insights are transforming cancer care. This work has been influential in advancing the field of personalized medicine. Dr. Kenner is dedicated to advancing medical science to improve patient outcomes and is actively involved in several international research collaborations to explore new therapeutic avenues.

Dr Ian Sinha is a Consultant Respiratory Paediatrician at Alder Hey Children's Hospital and Honorary Professor of Child Health at the University of Liverpool.
