Research Topics
1. Utilization of disaster wastes as geo-materials
A large amount of disaster wastes were caused by the great east Japan
Earthquake. Compaction, CBR and direct shear tests were conducted on thedisaster waste obtained from several sites at Tohoku region. An innovative
approach by using compost containing Halo bacteria/salt tolerance bacteria
was tested to restore the saline soil.
It was found that the disaster waste has a similar strength in comparison withusual sandy soil. The disaster waste contains organic waste such as wood
Disaster wastes
chip. It was considered that the organic waste will affect on the strength ofthe disaster waste for a long term. It was also found the compost is useful for reducing the excessive salts
from the soil.
2. Geo-environmental improvement techniques using microorganism for sustainable development
Various geo-environmental issues have occurred in regional and global levels. Utilization of wastes andremediation of contaminated soils are examples of geo-environmental problems. When waste material isutilized as geomaterials, it is required to apply any treatment for reducing the harmful substances. From aviewpoint of reducing environmental load, a method with low cost and without using special chemicals isneeded for sustainable development.
A remediation method by using aerobic or anaerobic fermentation is applied. The effect of compostingwith aerobic or anaerobic fermentation was discussed based on the test results. It is concluded that theanaerobic fermentation with organic matter, effective microorganism resources, and leaf mold is very
effective for remedying the contaminated soil with hexavalent chromium.

system identification theories such as Realization theory. Developed techniques make measurement
operations ‘on-line’ by ICT-aided computerized-operations from data collection to showing results ofanalysis. The system demonstrates high accuracy of identification and its practicability throughapplications to the several actual bridges.

A simple monitoring system 'Vehicle Intelligent Monitoring System' has been proposed for inspecting
road surface conditions objectively, promptly and inexpensively. The system estimates International
Roughness Index by capturing the vehicle's dynamic response from vertical acceleration. In this study,
VIMS has been introduced for road inspections in some countries.
3. Image Processing Techniques for Detecting Structural Damage on Surface
New robust automated image processing methods for detecting cracks in surface images of concrete

sequential image filters which are generated by evolutionary computation with genetic programming(: GP). The proposed method can be used for the accurate detection of cracks in surface images
recorded under various conditions. Moreover, the widths of the detected cracks can be quantified on
the basis of the spatial derivatives of the brightness patterns in sub-pixel resolution.

properties as electrodes of supercapacitors, were obtained according
to the synthesis conditions.

Various nanostructured carbon materials like carbon nanotubes andgraphene, nanoparticles were synthesized. CNT/SiC composite coating
showed much higher oxidation-resistance that single SiC coating. The dispersion of graphene with othernanosubstance could improve the surface area and electric conductivity.

transformation is widely used for controlling the microstructure of metal materials which play an importantrole in the infrastructure, and how to control this transformation is very important for designing thematerials. In order to control the transformation successfully, a deep understanding of the transformation isneeded. Therefore, I investigate the relation between the microstructure and the physical properties related
to the martensitic transformation.

Research in my laboratory focuses on understanding the mechanism of protein misfolding. Protein
folds into its intrinsic native coformation to exert its proper function. However, in some cases, proteins foldinto other tertiary structure and this misfold cause disease or inactive enzymatic function.
1. Elucidation of the oligomeric structure and structural chage in oligomerization of pore forming
toxines. Pore forming toxins associate into oligomer to form a pore in the membrane and cause a
disease. Oligomeric structures of the pore forming toxines were determined by X-ray crystallography.
Structural change in oligomerization was measured by small-angle x-ray scattering (SAXS).
2. Elucidation of the structure and enzymatic activity of the hyperthermophilic enzyme.
In some cases, enzyme from hyperthermophiles expressed in Escherichia coli shows much lower
activity than that of the native enzyme. Structural change between native and recombinant enzyme wasmeasured by SAXS. Biosci Biotechnol Biochem (2013) 77:679, Molecular Biosyst. (2012) 8:2050,
