I graduated from the Faculty of Medicine, Oita University in 2018. They subsequently completed five years of combined junior and senior residency, followed by two years of specialized training in arrhythmia therapy as a clinical electrophysiology fellow in the Department of Arrhythmia at the National Cerebral and Cardiovascular Center. Drawn to clinical research thereafter, I am now assigned to the Center’s Department of Data Utilization Promotion, where they conduct studies using national health-insurance claims databases and Diagnosis Procedure Combination (DPC) data.
