My research interest is auditory and affective neuroscience.

Specifically, I focus on experiments with music stimuli, although I sometimes use pure tone and voice stimuli. In general, emotion may exist in order to promote adaptive behavior such as escape from fearful situations and reward from delicious food. However, humans experience emotion and reward from music despite the fact that music does not have adaptive value and consists of simply a sequence of tones unfolding over time. Through the study of such a mysterious relationship between music and emotion, I aim to understand human emotion mechanisms.

In my past research, I examined the relationship between subjective reports of emotion, autonomic nervous system activity, and psychoacoustic features of music calculated using a music information retrieval method. Now in CiNet, I work on a project that examines the relationship between subjective reports of personality, brain responses, and text features of twitter posts. Although the research topic is different from my past research, I continue to examine the relationship between psychological responses, physiological responses, and physical features of real-world object. Furthermore, I continue to develop sophisticated studies of emotion using computational method and mathematical models.
