Joseph P. Bressler is an Associate Professor at Johns Hopkins University, jointly affiliated with the Bloomberg School of Public Health and the Krieger School of Arts and Sciences. He is a member of the Department of Environmental Health and Engineering and conducts research at the Kennedy Krieger Institute in Baltimore, Maryland. His work bridges public health, neuroscience, and molecular toxicology, focusing on environmental impacts on brain development. Education: PhD, Rutgers University, 1978 Dr. Bressler’s research centers on neurotoxicology, particularly how environmental pollutants such as lead, cadmium, and aluminum disrupt metal transport systems and affect neurodevelopment. His laboratory investigates the role of iron and other metal transporters at the blood-brain barrier and in glial cells, revealing mechanisms of metal uptake and toxicity. His work has implications for understanding autism, fetal alcohol syndrome, and other neurodevelopmental disorders. His recent publications highlight ongoing research into metal homeostasis, cytotoxicity in cancer and neuronal cell lines, e-cigarette aerosol variability, and epigenetic changes in sex chromosome aneuploidies. The research spans molecular mechanisms, in vitro models, and human health outcomes, demonstrating a multidisciplinary approach to environmental health. Scientific Contributions: Elucidated how lead and cadmium hijack iron transporters to enter the brain Demonstrated aluminum activation of iron uptake pathways in glial cells Investigated flavoring agents like ethyl maltol in enhancing metal toxicity Explored epigenetic and behavioral impacts in rare genetic conditions Dr. Bressler has advised numerous researchers and collaborators across disciplines. His work has been supported by federal and institutional grants, though specific funding details are not provided in the source text. He actively publishes in high-impact toxicology and environmental health journals, with research cited in policy and public health discussions. He leads a research laboratory focused on cellular and molecular mechanisms of neurotoxicity, utilizing in vitro models of the blood-brain barrier, astrocytes, and neuronal cell lines. His team collaborates widely across neuroscience, public health, and environmental engineering domains.
