Dr. Atsuko Imai-Okazaki, M.D., Ph.D., M.P.H., a Division Head of Genomic Medicine Research at the Medical Genomics Center of National Center for Global Health and Medicine, obtained her M.D. degree from Kobe University in 2005 and subsequently received a Ph.D. degree in medicine from Osaka University and M.P.H. degree from University of Manchester in the UK. She is a cardiologist and a specialist in clinical genetics. Dr. Okazaki obtained the skills of bioinformatics, biostatistics, and statistical genetics at McGill University, Baylor College of Medicine, Harvard Medical School and Rockefeller University. She is also an adjunct professor at McGill University, a guest investigator at Rockefeller University, and an adjunct lecturer at Intractable Disease Research Center at Juntendo University.

Research Interests

By combining statistical genetics, clinical genetics and computer science, Dr. Okazaki developed a novel statistical method to prioritize sequence variants using Hamming distance (Sci Rep 2015). One of the clinical applications of her method is a mitochondrial disease cohort in Japan. Dr. Okazaki is in charge of genetic analysis of ~2400 mitochondrial disease patients. She has found causative mutations of mitochondrial diseases and assessed the relationship between long-term prognosis and genetic background of mitochondrial cardiomyopathy (Int J Cardiol 2016, J Human Genet 2016, Hum Mutat 2017, J Pediatr 2018, Int J Cardiol 2019, Human Mutat 2019).
