Academic Degree
ph. D
Field of Specialization
Soft matter physics, statistical physics
Outline Activities
I have been working on interfacial and dynamical properties of soft visco-elastic solids, such as adhesion of soft rubber and sliding friction of gels. I have been also interested in mechanical metamaterials.
Research
Research Interests
  • Interfacial mechanics in softmatter (adhesion & friction)
    Laboratory experiment of earthquake phenomena
    keyword : adhesion, friction, tribology, fracture, earthquake, stick-slip, gel, pressure sensitive adhesives
    2004.10~2015.03.
Current and Past Project
  • Recently, a new type of earthquake, called slow earthquake, has been discovered due to the development of new observation techniques like GPS. In this project, we have been studying slow earthquakes to understand the basic mechanisms based on geophysical or physical approaches.
  • In order to understand the basic mechanisms of earthquake occurrence, we develop laboratory models. We try to elucidate the details by performing In-situ visualization during the processes.
  • By mimicking ultra-low friction and wear articular cartilages, we develop hydrogel-based artificial articular cartilages.
