Dr. Lein received her PhD in Pharmacology and Toxicology from the State University of New York at Buffalo, and completed postdoctoral training in Molecular Immunology at the Roswell Park Cancer Institute in Buffalo, NY. Currently, she is Professor of Neurotoxicology and Chair in the Department of Molecular Biosciences in the University of California, Davis School of Veterinary Medicine, and a faculty member of the MIND Institute at UC Davis. Dr. Lein is the PI and Director of the NINDS-funded CounterACT Center of Excellence, former Director of the NIEHS-funded training program in environmental health sciences, and Director of the Career Development Program for the NIEHS-funded Environmental Health Sciences Center. Her research focuses on molecular and cellular mechanisms by which environmental chemicals interfere with neurodevelopment and neural function to contribute to environmentally induced diseases. Environmental contaminants currently being investigated in her laboratory include persistent organic pollutants, specifically PCBs and PBDEs, traffic-related air pollution, orphanophosphorus pesticides, and seizurogenic chemical threat agents.
