Philip J. Landrigan, MD is Professor of Environmental Medicine and Pediatrics and Dean for Global Health in the Icahn School of Medicine at Mount Sinai. For four decades, he has been a thought leader in environmental medicine. His early studies of lead poisoning contributed to the US government decision to remove lead from paint and gasoline. A landmark study he led at the National Academy of Sciences defined children’s unique susceptibilities to pesticides and other toxic chemicals and catalyzed fundamental revamping of US pesticide law. He guided EPA in establishing the Office of Children’s Health Protection. In New York, Dr. Landrigan has directed medical and epidemiologic follow-up of 20,000 9/11 rescue workers. He co-chaired the Lancet Commission on Pollution & Health which showed that pollution causes 9 million deaths annually. He and Mary Landrigan published Children and Environmental Toxins: What Everyone Needs to know (Oxford University Press) in February, 2018.
