From Clinical Questions to Testable Research

As a physician and biostatistician, I turn questions that arise at the bedside into testable research using study design, biostatistics, and AI, and feed the results back into clinical decisions. Through ongoing collaborations — in drug safety, emergency and critical care, and cerebrovascular disease — and through studies I lead as principal investigator, I explore individual differences in treatment effect and risk, evidence generation from limited data, and privacy-preserving international collaboration.

Three Questions

Guiding Questions
01

For the same treatment or drug, who benefits and who faces higher risk?

Capturing differences by patient background, co-medication, severity, and clinical setting that average effects or safety signals cannot reveal.

02

How can we build decision-grade evidence from limited clinical data?

Combining systematic reviews, meta-analysis, real-world data, and external validation.

03

How can we learn and validate across institutions and borders while protecting patient data?

Building a research infrastructure for multi-site reproducibility and validation through federated learning and data harmonization.

Background

Background

After graduating from Nagoya University School of Medicine and completing initial clinical training, I turned to biostatistics out of an interest in supporting clinical decisions from the methodological side. I earned my PhD (Medicine) at Nagoya University and spent five years as a practicing biostatistician at the Center for Advanced Medicine and Clinical Research, Nagoya University Hospital, supporting clinical research across many fields in both design and analysis.

Beginning VigiBase research with a team at the University of Caen (France) in 2024 marked a shift from supporting others' work to leading my own questions. After Kyoto University (Biostatistics) in 2025, since 2026 my primary post has been Junior Associate Professor in the Department of Biostatistics, Nagoya University Graduate School of Medicine, concurrently serving as Project Junior Associate Professor at Kyoto University and Visiting Junior Associate Professor at Fujita Health University — continuing research that connects clinical practice and statistics in Japan and abroad.
