Our research focuses on human-to-human communication, measuring multiple biological signals such as brain activity, autonomic nervous system responses, and eye gaze, and quantitatively describing them using time-series and network analysis. In particular, we aim to understand "discrepancies in understanding, attention, and perception" during conversations and collaborative work as state transitions, clarifying the triggers and transitions of these state transitions through the analysis of biological signal data, and establishing descriptive methods for these transitions.
The appeal of research
Since prehistoric times, we have lived by communicating with others. The appeal of this research lies in its ability to make visible the subtle changes, such as misunderstandings and miscommunications, that occur within this universal and familiar activity, through the latest biosignal measurement and data analysis.

Research Contents
My research focuses on human communication. I measure multiple biosignals—such as brain activity, autonomic responses, and eye gaze—and quantitatively describe them using time-series and network analyses. In particular, I regard subtle “misalignments” in understanding, attention, and perception during conversation and collaborative work as shifts between states, and aim to clarify what triggers these shifts and how they unfold through the analysis of biosignal data, while establishing robust methods to describe them.
Attractive Factors of My Research
My research is driven by a simple idea: humans have lived by communicating with one another since long before written history. What makes this work compelling is the opportunity to bring subtle, often hard-to-notice changes—such as misunderstandings and misalignment—closer to something we can see, by combining state-of-the-art biosignal measurements with data analysis.
