Environmental Engineering Science
Environmental challenges such as climate change, natural disasters, growth of energy consumption, shortage of natural resources, are affecting people both globally and locally. This situation is creating demand for human resources who can resolve these challenges. The university’s Environmental Engineering Science program aims to educate engineers and researchers who can contribute to establish safe and sustainable society in harmony with the environment through collaboration between Chemical & Environmental Engineering and Civil & Environmental Engineering.
The program conducts academic activities from two aspects: 1) environmental/energy conservation and 2) infrastructure management/disaster prevention. From the environmental and energy perspectives, the program develops engineering knowledge and skills in environmental, energy, material, and biological fields for realizing a sustainable society based on chemical engineering. From the infrastructure and disaster prevention perspectives, the program develops human resources for planning, design, construction, and maintenance of safe and sustainable infrastructure and social systems.

Numerical Simulation for Earthquake-Induced Landslides
Development of effective procedures to predict earthquake-induced landslides accompanying catastrophic slope failure is one of the important issues to be resolved in our ongoing efforts for improvement of disaster prevention. We have proposed a new elasto-plastic constitutive model to simulate strain-softening behaviors of sensitive soils under cyclic loading, which has been applied to the finite element simulation of a lot of past catastrophic landslides caused by each earthquake motion. We are trying to analyze the mechanism of catastrophic failure in detail with clarifying the relationships between the slope stability and the strain-softening characteristics of contained soils.
Development of Steam/Hydrogenation Hybrid Process for High-Grade Oil Production from Biomass
Biomass resources such as agricultural wastes or animal mature are widely spread, causing high collection and transportation costs and hindering efforts to establish their large scale utilization. To utilize this biomass requires the development of small-scale plants with high economic efficiency. We are working to establish an economically efficient plant by developing a small-scale process for unutilized biomass, which produces high-grade oil and electricity matching with local demand.
Daily life in my laboratory is very busy, because we must organize everything from research planning to design, construction and operation of experimental setups and summarization of experimental results. But, I like my laboratory life. That is because being busy also leads to my own growth. Whenever I failed and felt down, my supervisor and lab members always cheered me up. They also let me know “give someone a fish and you feed them for a day; teach someone to fish and you feed them for a lifetime”.
