Welcome to Tetsuo Yamaguchi's website!

Last update: 29 Mar 2016
I was born in Kumamoto city, Kumamoto pref., Japan in Dec. 1971.
After working for a company, I started to study soft matter physics
at the University of Tokyo and received ph.D in 2007. After that,
I worked as a post-doc in prof. C. Creton's group of ESPCI (Paris),
worked as an assistant professor in prof. M. Doi group in Tokyo,
and I am now working as an associate professor in Kyushu University.
(My CV is here )


1. Research interest My current interest lies in the physics of adhesion and sliding friction of soft viscoelastic materials like elastomers or gels. My approaches are phenomenology (continuum theory) and experiment (optical observation), trying to understand the dynamical process of local deformation and fracture of such materials. In future, I hope to develop fundamentals of non-equillibrium physics for the above phenomena.

Research topics
- Adesion/debonding and cavitation dymanics in soft viscoelastic materials (experiment, theory).
- Mechanism in adhesion-friction of gecko (experiment, theory).
- Pattern formation in sliding friction of sticky gels (experiment, theory).
- Laboratory experiment of fast and slow earthquakes (experiment, theory).
- Buckling phenomena in swelling process of hydrogel particles (experiment).
- Geometry, topology, and fracture of model crosslinked polymer network (experiment).
- High-precision monitoring of buckling, fracture and slip (experiment).
