Thyroid Hormone Disruption and Neurodevelopment

Dr. Noriyuki Koibuchi obtained his M.D. and Ph.D, at Gunma University, Japan. Then, he worked as a postdoctoral fellow in the Department of Neurobiology and Behavior at Rockefeller University. He then became the Assistant Professor of Physiology at Dokkyo University School of Medicine, Japan. Subsequently, he became a Visiting Assistant Professor of Medicine in the Division of Genetics at Brigham and Women’s Hospital and Harvard Medical School. Then, he was appointed to be a Professor and Director for the Department of Integrative Physiology at Gunma University Graduate School of Medicine. Dr. Koibuchi’s area of expertise and main interest concern the molecular mechanisms of thyroid hormone action in the central nervous system. He is a member of the Endocrine Society, Society for Neuroscience, and Society of Toxicology.Dr. Paul M. Yen received his M.D. from Johns Hopkins University and trained in internal medicine at University of Chicago. After a postdoctoral fellowship in endocrinology at NIH, he served on the faculty at Johns Hopkins and Harvard. He was also section chief at NIDDK and NIH before he joined Duke-NUS Graduate Medical School in Singapore as an Associate Professor. He is the Head of the Laboratory of Hormonal Regulation in the Cardiovascular and Metabolic Disorders Program; it is a lab that uses molecular, biological, and genomic approaches to study the hormonal regulation of transcription, particularly thyroid hormone (TH). His particular research interests include: hormonal regulation of hepatic autophagy and lipid metabolism in non-alcoholic fatty liver disease (NAFLD), as well as epigenetic regulation of metabolic genes by thyroid hormone.
