Toshiaki Dobashi, PhD, Professor, Department of Chemistry and Chemical Biology, Gunma University. Vice President of The Society of Rheology, Japan.. Associate Editor, Journal of Biorheology. Toshiaki Dobashi studied polymer physics at Hokkaido University, Japan and received his PhD in 1982 studying thermodynamic properties of multicomponent polymer solutions. From 1982 to 1988 he was Assistant Professor at Gunma University working on rheology of blood and blood vessels, and from 1988 to 2001 he was Associate Professor working on chemistry, physics and biological applications of microcapsules by means of light and ultrasonic scattering. Between 1994 and 1995 he joined the group of Prof. Benjamin Chu at State University of New York at Stony Brook as visiting associate professor for characterization of core-shell materials by synchrotron X-ray. Since 2001 he has been at the current position working on microrheology of soft matter such as gels, nanoparticles and cells. Rio Kita, PhD, Associate Professor, Department of Physics, Tokai University. Rio Kita studied polymer physics at Gunma University, Japan and received his PhD in 1999 studying critical phenomena of polymer and surfactant solutions. From 1999 to 2002 he was a postdoctoral researcher at RIKEN (The Institute of Physical and Chemical Research), Japan, working on characterizations of biopolymer solutions. In 2002 he joined the group of Prof. Wegner at MPI-P (Max Planck Institute for Polymer Research/Mainz), Germany where he was responsible to the service group of polymer analysis. Since 2005 he has joined the group of RGMS (Research Group of Molecular Complex Systems) at Tokai University, Japan. His current research interests include transport phenomena of polymers in a temperature gradient condition, dynamics of structure formation of polymers, and characterization of polymer solutions in dilute and semi-dilute regions.
