Research Overview

I am engaged in informatics research aimed at applications in patient safety, community healthcare, and pharmacy education. In settings where medications play a central role—such as residential care facilities, healthcare institutions, pharmacies, and educational environments—a wide range of events that shape the quality of practice occur on a daily basis, including incidents, interactions with patients, and learning processes. However, these events are not always recorded or captured in forms that can readily be used for analysis or support, and in many cases they are not sufficiently recognized as information in the first place. Even when they are documented, they often take the form of free-text narratives or complex interactions, making systematic understanding and use difficult. I seek to structure such events and practices arising in real-world settings through informatics approaches, including natural language processing (NLP), and to connect them to analysis and practical support. I also place importance on ensuring that the knowledge gained is not limited to description or evaluation alone, but is translated into forms that can contribute to learning and improvement in practice. My main research themes are as follows. 1. Research on patient safety I study medication-related incidents in residential care facilities and healthcare institutions, with the aim of clarifying their occurrence patterns and contributory factors, while also developing analytical infrastructures that can extract such factors from the free-text narratives of incident reports. By combining human-factors perspectives with natural language processing, I aim to deepen our understanding of incidents and to build systems that connect the resulting insights to recurrence prevention and learning. 2. Research on community healthcare I investigate how patient-reported data, symptom information, and other medical and pharmaceutical data can be used to support better information sharing and more appropriate forms of support for issues arising in community-based settings, including healthcare, long-term care, and pharmacies. My goal is to develop knowledge and systems that can be used in practice to improve the quality of care across healthcare, long-term care, and everyday life, and to contribute to continuous improvement and learning in local communities. 3. Research on pharmacy education I focus on learning processes in medication counseling and experiential training, and aim to enhance educational evaluation and learning support by analyzing communication and reflective practice as information. By utilizing diverse forms of data, such as audio, language, and video, as well as large language models (LLMs), I explore new methods for evaluation and support in pharmacy education while seeking to build systems that enrich learning in educational settings. What these studies share is the perspective of re-examining complex events and experiences arising in practice as information, structuring them, and linking them to analysis, support, and ultimately learning. Across the domains of pharmacy, healthcare, long-term care, and education, I aim to reinterpret practice-based challenges through the methodologies of informatics and to connect them to improvements in practice and the creation of new value.
