We study soft-matter physics and biophysics theoretically and numerically. Our main target is the stricture formation of biomembrane and dynamics of complex fluids under various conditions. We develop membrane models and hydrodynamics simulation methods. We found the shape transitions of red blood cells and lipid vesicles in shear and capillary flows using mesoscale hydrodynamic simulations: discocyte-to-parachute, stomatocyte-to-prolate, and prolate-to-discocyte, etc. We also clarified the membrane tubulation by the BAR proteins. Moreover, we investigated the fracture process of polymer materials and cavitation in Karman vortex.

Membrane structures induced by banana-shaped protein rods: periodical bumps, hexagonal network, spherical bud, and cylindrical tubules.
