The Geosphere Environmental Systems Engineering Lab studies the environment of the geosphere, the space extending from the ground surface where people live down into the subsurface. People have developed society by exploiting and using the geosphere, but in the process problems such as land subsidence, changes in the groundwater environment, soil contamination, and sediment disasters have also arisen. Geosphere environmental problems are hard to detect in their early signs and often appear only after a long time, so appropriate evaluation and monitoring are needed at every stage from planning to maintenance. Building on geotechnical and rock engineering, the lab explores technologies for development and conservation in harmony with the environment, making use of information technologies such as satellite remote sensing, 3D data, and GIS.

The Environmental Fluid Dynamics Lab studies water environment problems that occur in natural water bodies such as seas, rivers, and lakes. Water is essential not only to humans but to all living things in nature, yet population growth and global warming are predicted to cause a shortage of good-quality water resources. At the same time, warming is said to intensify changes in rainfall and strengthen tropical cyclones, raising concern about increasing flood damage. Through developing technologies to conserve and restore the water environment, clarifying the mechanisms by which the water environment deteriorates, and investigating disasters such as floods, the lab searches for ways to achieve both disaster prevention and environmental conservation.

The Urban Environmental Engineering Lab conducts research on what is generally called water environment engineering. The water environment consists of diverse elements such as water quality, water quantity, organisms, bottom sediment, waterfronts, and landscape, and all of these need to be conserved as a whole. To that end, the lab develops integrated watershed water management methods that take a bird's-eye view of the water environment and water cycle, and it also examines the role of local water facilities such as sewage treatment plants. Using a range of technologies and systems for environmental purification, ecosystem conservation, comprehensive water management, and wastewater treatment, the lab works on comprehensively conserving the water environment.

The Urban and Transportation Engineering Lab studies environmental problems such as climate change, global issues such as energy and the link between development and poverty, and urban problems such as soaring housing prices and traffic congestion. Its subjects are the complex problems cities face, including aging and population decline, health and welfare, education, disasters, and the design of transportation systems. Using a multifaceted, interdisciplinary approach that draws on urban engineering, transportation engineering, and economics, the lab tackles these problems through both theory and empirical work, and also makes realistic, effective policy recommendations. The lab's mission is to improve citizens' lives through new infrastructure and technology and to make cities run better.

The Healthy Building Environment Lab theoretically analyzes the movement of heat, mass, and air in cities and buildings, and elucidates the physical phenomena of the built environment. Building on building physics, the lab works on the design of living environments that excel in energy saving, durability, and well-being, and on the design of building functions that use advanced equipment systems and renewable energy. Put simply, the lab uses numerical simulation techniques to scientifically design buildings that are comfortable to live in and kind to the global environment. Because the urban and building environment consists of a human system, a building system, and an equipment system, it is necessary to understand people's physiological and psychological needs, design heat, light, and air passively, and then control them actively with equipment. The topics covered include passive systems and highly efficient equipment systems for energy saving, the design of living environments and functions in advanced buildings, temperature and humidity control and condensation prevention technologies for highly durable buildings, dynamic prediction and evaluation of the building environment based on coupled analysis of heat, mass, and air movement, and prediction of future energy consumption of cities and buildings and measures against global warming. The lab also continues its research on developing next-generation, high-performance buildings that combine insulation, heat shielding, airtightness, ventilation, heat collection, heat rejection, heat storage, and humidity control, and on numerically showing how facade design affects a building's thermal environment. The lab's Assistant Professor analyzes the thermal environment of buildings using future weather data that incorporates climate change due to global warming, and is conducting research that measures the quality of architecture from a well-being perspective, including factors such as greenery, biodiversity, sustainable living, and community. Another pillar of the lab is developing a thermal environment simulation model using urban information from PLATEAU, the 3D city data, and developing and implementing ThermalOne, a building thermal environment simulation software the lab has nurtured.

The Sustainable Building Energy Lab conducts research on reducing the energy consumed in buildings. The building sector accounts for one third of society's total energy consumption, so cutting it is an important theme for achieving a decarbonized society. In its urban-scale research, the lab forecasts the future energy consumption of buildings and, by combining supply equipment such as solar power generation, storage batteries, and hydrogen fuel cells, sketches a vision of future urban energy. In its research on human behavior, the lab conducts repeated experiments to verify how information delivered through smartphone apps and IoT tools can steer people's behavior toward energy saving.

The Stringology Lab uses the term "strings" for all kinds of sequentially arranged data, and studies the theory of algorithms that process them at extremely high speed and with minimal space. The targets include text, time series, numerical sequences, labeled trees and graphs, and two-dimensional arrays. By combining combinatorics on words, which explores the mathematical properties of strings, with state-of-the-art algorithms and data structures, the lab aims to process large-scale data efficiently. The lab's website notes that string-processing problems appear frequently in competitive programming as well, and are attracting attention.

The Mathematical Engineering Lab aims to clarify the mathematical form of a wide range of problems in computers and digital communications, and to derive universal solutions based on that understanding. Its research themes are basic theories such as learning theory, machine learning, information theory, information geometry, communication theory, network theory, and nonlinear systems theory, as well as their applications. Examples of applications include cyber attack detection on the Internet, super-resolution, pattern recognition, CDMA communications, and ultra-high-resolution analog-to-digital conversion. On the lab's website, the Takeuchi, Jitsumatsu, and Hanaka labs are introduced together under the name "Mathematical Engineering and Information Circuits Lab."

The Algorithm Theory Lab studies the theory of distributed algorithms, in particular distributed coordination of swarms of autonomous mobile robots and fault-tolerant distributed algorithms. On the lab's website, it is introduced under the name "Theoretical Computer Science Group (Yamauchi Lab)." Students' bachelor's and master's theses include titles dealing with gathering, search, and merging of robot swarms.

The Information Security & Multimedia Security Lab studies security technologies that protect society. Based on the concept of the "Internet of Things" (IoT), the lab considers that in a society where not only people but also things are connected to one another, an attacker taking control of the network could cause major damage. The lab is affiliated with the Department of Electrical Engineering and Computer Science in the School of Engineering, and the Department of Information Science and Technology in the Graduate School of Information Science and Electrical Engineering.
