What will the modern online society be like, and how will the Internet change us? These are not only technological issues, but also cultural and intellectual issues. We will study the characteristics and problems of the Internet society = multicultural information space from the viewpoint of informatics. In particular, I am interested in research on media literacy education, eLearning, ePortfolio, and other educational engineering methods for better self-realization in the Internet society.
My recent research interest is to analyze big data on the Internet using machine learning techniques such as text mining.
I am also continuing my research on computer music and electronic musical instruments from the viewpoint of acoustic processing and musicology.

• Informatics (Internet, Information Media Theory)
• Educational Engineering (especially ePortfolio and eLearning)
• Electrical and Computer Engineering (signals and systems, communications, data science, stochastic processes, machine learning)
• Speech information processing (speech recognition, acoustic modeling, dialogue systems, robustness)
• Digital Signal Processing (especially computer music, acoustics, multimedia)
• Applied Linguistics (Intercultural Communication)

We aim to analyze modern society in terms of its various characteristics as media.

We use data science to analyze internet posts such as Twitter, blogs, and the web.
At the same time, students will learn analytical methods and modeling of media information such as images and video, and apply them to actual data for analysis.

Taking popular music as a theme, students will study electronic instruments such as synthesizers, samplers, and drum machines, as well as studio sound effects techniques. Students will learn about contemporary artists while gaining a deeper understanding of relevant issues in music history from a variety of sources, including original subscriptions, field recordings, film music, and broadcasts.
