The major objective of our laboratory is to construct and develop a discipline that precisely designs materials to match human sensibility from the molecular level via rheology (Molecular psychorheology). To this purpose, we are establishing quantitative evaluation methods for sensibility, and developing techniques to elucidate and control the correlation between rheology and molecular dynamics, with the aim of freely controlling rheology.
