The lab calculates the behavior of electrons in magnetic materials and also works on information visualization.

Tokii Lab studies the behavior of electrons through theoretical calculations in order to understand the properties of magnetic materials. Magnetic materials are used in recording media that store various kinds of data such as text, numbers, images, and sound, as well as in components of devices. Research themes listed for the lab include computational physics and computer simulation, as well as information visualization and digital humanities.

The lab studies human-in-the-loop machine learning as well as graph and time-series data analysis.

Assistant Professor Hiroyoshi Ito of the Fusion Intelligence Design Lab works on human-in-the-loop machine learning, graph data mining, and time-series data analysis. Ito is one of the translators of Human-in-the-Loop Machine Learning: Active Learning and Annotation for Human-Centered AI. Ito's publications include papers on crowdsourcing and future prediction for social networks.

The lab explores how to use computers and multimedia in education.

Osawa Lab studies how computers and multimedia can be used in educational settings. Some time has passed since the subject "Information" was introduced in high schools, and the way computers and multimedia are used in educational settings is changing. Exploring ways of using them that suit the times is the lab's main research theme.

会議科学（陳 映廷） (introduction coming soon)

Meeting science, teamwork, facilitation, complex problem solving, team cognition, analysis of collaboration, and intervention design: cognitive facilitation in teams engaged in complex problem solving; self-facilitation, in which members themselves coordinate the process and stimulate discussion, and how it improves meeting quality and creative collaboration; effects of thinking styles, trust, and task complexity on team dynamics, analyzed through empirical approaches and tool design; development and evaluation of analog and digital support tools (e.g., in-meeting visualization tools) to build support technologies and theoretical insights applicable to real-world teams

The lab explores search systems that connect people and knowledge, from information seeking to picture book recommendation.

The Web Information Systems Lab studies methods for discovering and organizing knowledge from a wide range of information, such as the Web, literature, and manuals. The lab also analyzes what people need in what situation, for example whether they want the answer to a problem or want to learn from related information. It aims to realize knowledge and information retrieval systems that connect what people want to know with what the world knows. Its research themes also include interfaces for information seeking and picture book recommendation.

The lab uses machine learning to create information retrieval algorithms.

The Knowledge Acquisition System Lab (KASYS, the Kato-Pham Lab) conducts research on information retrieval. Its main research areas include retrieval models and ranking, learning to rank, search intent estimation, and recommender systems. The lab often conducts research that uses large language models and machine learning to create high-performing algorithms. As of 2026, the lab is based at the University of Tsukuba and the National Institute of Informatics, and belongs to the University of Tsukuba Information Retrieval Research Group.

A lab that examines social issues through library management and policy.

The Koizumi Lab studies, from the perspectives of management and governance, how libraries operate and provide knowledge, information, technology, and media to citizens. From three levels (national policies and institutions, the management of regions and organizations, and individual information behavior), the lab considers how libraries can solve social issues. Focusing on libraries in the Nordic countries, the United States, and Japan, the lab conducts policy analysis and case analysis. The lab is also interested in collection development and evaluation, which involves assembling library materials and assessing them.

A lab in archival science that studies the preservation and use of local public records and historical materials.

The Shirai Lab specializes in Japanese archival science and studies public records (administrative documents) and historical materials (old documents, or komonjo) managed by local communities. The lab mainly investigates their structure and information, as well as measures for their preservation and use. The lab also conducts research through practical activities, such as preserving documents, records, and materials related to the damage caused by the nuclear power plant accident in the Great East Japan Earthquake, and rescuing public records in Joso City, Ibaraki Prefecture, after the Kanto-Tohoku Heavy Rain flooding.

A lab that studies media use by children and adolescents and its effects on their development.

The Suzuki Lab studies how children and adolescents use media and how this affects their development. The subjects are print media such as books, newspapers, and manga, and video and electronic media such as video games, television, and the Internet. The lab examines the effects broadly, from both the academic and the interpersonal and psychological aspects.

The lab explores older adults and libraries, and learning support.

Professor Saori Donkai's lab conducts research on "older adults and libraries" and "knowledge and information infrastructure." In the area of older adults and libraries, the lab deals with the Research Group on Super-Aged Society and Libraries, dementia-friendly libraries, and the information-seeking behavior of older adults. In the area of knowledge and information infrastructure, the lab deals with learning commons, learning support, and student assistants.
