Chair-Elect
Hiraku Kumamaru
Yokohama City University, Graduate School of Data Science
Dr Hiraku Kumamaru graduated from the University of Tokyo Faculty of Medicine and, after clinical training, developed an interest in health policy, working as a researcher at the Health and Global Policy Institute. He went on to study at the Harvard School of Public Health, earning MPH, MS, and ScD degrees while training in health-policy foundations, claims- and registry-based clinical research methods, and applied and methodological pharmacoepidemiology. Returning to Japan, he took part in building, operating, and analysing registries based on the National Clinical Database (NCD) at the University of Tokyo, focusing on data generation and the systems that support data reliability. Since April 2025 he has been at the Graduate School of Data Science, Yokohama City University. His work centres on real-world data, including claims, DPC, electronic health records, and registries, and on understanding their generation, accuracy, and the biases that arise from database characteristics, which he regards as a common foundation for high-quality pharmacoepidemiological research.
