Dr. Fei Chen, PhD, is a tenured professor at the Stony Brook Cancer Center and the Department of Pathology at Stony Brook University. He has over 20 years of experience in epigenetic and genetic alterations, metabolic reprogramming, and the identification and targeting of cancer stem cells in chemical carcinogenesis, including heavy metal–induced carcinogenesis. His laboratory was the first to identify the reduced capacity for reactive oxygen species (ROS) generation in arsenic-induced malignantly transformed cells. Currently, his lab is investigating the oncogenic roles of NRF2 and KLF4 signaling in response to mixed-metal exposure, 1,4-dioxane, and other environmental carcinogens.

Giselle Cerchiaro is Professor of Chemistry and Biochemistry at the Federal University of ABC (UFABC), São Paulo, Brazil, where she leads the Metal Biochemistry and Oxidative Stress Laboratory. She holds a PhD in Chemistry from the University of São Paulo (2005), with part of her doctoral work at Università di Roma Tor Vergata, and was a visiting researcher in Rome (2019). Her research addresses bioinorganic chemistry of copper, reactive oxygen species in cell signaling, and metal dyshomeostasis in neurodegeneration.

Jennifer Freeman is a Professor of Toxicology in the School of Health Sciences, faculty affiliate in Environmental and Ecological Engineering, and courtesy faculty in the Department of Public Health at Purdue University. She is also the Assistant Vice President for Research Development in the Office of Research at Purdue University. The Freeman Environmental Molecular Toxicology Laboratory addresses the underlying molecular mechanisms of neurotoxicity of environmental chemicals in the developmental origin of health and disease (DOHaD) paradigm using the zebrafish model system. This research is supported by the National Institutes of Health (USA) and other entities. She is the President of ISTERH, has held multiple leadership positions in the Society of Toxicology, and served on committees for the National Academies of Sciences, Engineering, and Medicine (USA).

An Associate Professor and Vice-Chair of Education at Brown University. Her lab uses the zebrafish model to study how genetic mutations and environmental contamination disrupt the development of the brain, heart, and vasculature. Prof. Plavicki also directs the Pathology and Laboratory Medicine Internship Program at Brown University and co-leads the Research-Clinical Experiences in Neurology, Neuroscience, and Neurosurgery Program (NIH R25) at Brown.

Nishant Sharma is a postdoctoral research fellow in the Division of Pharmacology and Toxicology at the University of Texas in Austin. His current research primarily focuses on mechanistic studies of metal-induced toxicity. He utilizes a combination of sophisticated cell-based assays, tissue-specific knockout mouse models, and human-derived samples to understand the mechanisms of manganese (Mn) induced toxicity.

Assistant Professor at NOVA School of Sciences and Technology and coordinator of the Analytical Techniques Development and Applications thematic line at LIBPhys. Holding a PhD in Physics from the University of Lisbon (2013), she is a recognised expert in Raman spectroscopy and X-Ray Fluorescence, specialising in portable instrumentation design. Her current research focuses on biomarker detection for Cancer and Parkinson's disease, spectroscopic tools for dental diagnostics and in vivo Raman analysis, and the impact of environmental contamination on human health. She serves on the Advisory Board of X-Ray Spectrometry (Wiley) and as Editor of the Encyclopedia of Analytical Chemistry (Wiley). Throughout her career, she has co-authored over 120 scientific publications and supervised 24 master and PhD theses.

Dr. Mukhopadhyay is Professor of Pharmacology and Toxicology and Fellow of the James E. Bauerle Professorship at The University of Texas at Austin. His laboratory studies gene-environment interactions in neurological diseases, particularly transport mechanisms, neurotoxicity, and homeostatic control of the essential metal manganese. His work is routinely published in influential journals (e.g. PNAS, J Biol Chem) and supported by the National Institutes of Health. He is also the Vice President of ISTERH and has previously held leadership positions in the Society of Toxicology.

Wagner Tamagno is a biologist with a Master's degree in Pharmacology, with emphasis in immunopharmacology and psychopharmacology, and a PhD candidate in Toxicology at Purdue University, with emphasis in neurotoxicology and developmental toxicology. His research focuses primarily on the Developmental Origins of Health and Disease (DOHaD) associated with lead exposure, as well as ecotoxicology through multidisciplinary expertise and collaborations. He is a member of the Society of Toxicology, serving on the board of the Food Safety Specialty Section, and is also a member of the Metals Specialty Section and the Hispanic Organization of Toxicologists.

Xiang Xue, Ph.D., is an Associate Professor and Regents Lecturer at the University of New Mexico School of Medicine. His research examines how environmental toxicants drive inflammation and cancer. His lab uses molecular, metabolic, and translational approaches to uncover mechanisms and therapies. He is continuously NIH-funded, widely published, and recognized for advancing micronutrient biology in cancer. He is committed to mentoring, teaching, and national leadership in scientific service.
