We study soft-matter physics and biophysics theoretically and numerically. Our main target is the physics of biomembrane and cells 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 and the fracture process of polymer materials.
