Specializing in in-house production of radiopharmaceuticals, quality control, and system-level workflow design, he focuses on optimizing the entire operational framework of radiopharmaceutical practice, including PET tracer synthesis, QC, supply management, and education systems.
In recent years, his work has emphasized the development of sustainable operational systems in clinical settings by integrating troubleshooting experiences and practical knowledge into structured workflows and educational resources.
After graduating from the Faculty of Engineering at Tottori University, he pursued graduate studies in material and biological informatics at the Graduate School of Human Informatics, Nagoya University. He subsequently engaged in research and technical development in both industry and research institutions, including the National Institute of Advanced Industrial Science and Technology (AIST), the National Center for Geriatrics and Gerontology, and Nagoya University, and obtained a doctoral degree in protein chemistry. He is currently involved in the production and operational management of radiopharmaceuticals at Fujita Health University Hospital.

Nuclear Medicine Communications, Jul 28, 2026 Peer-reviewedLead authorLast authorCorresponding authorThis technical note reports threshold behavior of droplet release in automated [¹⁸F]FDG quality control. During routine operation of an automated QC system, small-volume dispensing showed unstable droplet release, resulting in misplacement on test media. Droplet behavior was sensitive to programmed dispensing volume: 0.011 mL frequently resulted in adhesion to the needle tip, 0.012 mL showed borderline behavior, and 0.013 mL restored stable release. The findings highlight the importance of periodic verification and adaptive adjustment of dispensing parameters in automated radiopharmaceutical quality control.

Journal of Nuclear Medicine Technology, Jul 21, 2026 Peer-reviewedLead authorLast authorCorresponding authorRoutine maintenance of a radio-HPLC detector system resulted in an unintended shift of the detector energy window from 511 keV to approximately 400 keV, causing substantial signal attenuation during radiopharmaceutical quality control. This report describes the incident, root cause analysis, and the role of technologists and site engineers in identifying and resolving the problem.

Operational Protocol for Sustainable FDG Production in Hospital-Based Radiopharmaceutical FacilitiesUnpublished Technical Report (Institutional Document), Apr, 2026 Lead authorLast authorCorresponding authorThis report presents a structured operational protocol for sustainable 18F-FDG production in hospital-based radiopharmaceutical facilities. The protocol integrates routine workflow, troubleshooting processes, and education-driven system design to ensure stable and safe production. Rather than treating operational issues as isolated events, this framework systematically converts troubleshooting experiences into standardized workflows and training resources. This approach enables continuous system improvement and transforms operational variability into structured system resilience in radiopharmaceutical practice.

Unpublished Technical Report (Institutional Document), Apr, 2026 Lead authorLast authorCorresponding authorThis report presents a structured operational framework for medical supply management in hospital-based radiopharmaceutical production environments without centralized SPD systems. The framework integrates demand forecasting, inventory control (including FEFO principles), supplier dependency assessment, and risk mitigation strategies. It emphasizes the dynamic interaction between procurement constraints, hospital policies, and production requirements. This approach highlights how supply constraints can translate into hidden operational burdens and provides practical strategies to enhance system resilience and continuity in radiopharmaceutical practice.

Post-Maintenance Verification Protocol for Radio-HPLC Systems in Radiopharmaceutical Quality ControlUnpublished Technical Report (Institutional Document), Apr, 2026 Lead authorLast authorCorresponding authorThis report presents a practice-based verification protocol designed to address the risk of detector configuration drift following maintenance in radio-HPLC systems used for radiopharmaceutical quality control. The protocol aims to strengthen quality assurance in both routine operations and validation processes.
