1. Modeling of Membrane

• Meshless membrane model (for larger scale than membrane thickness)
• Solvent-free molecular model for lipid bilayer (for length scale of membrane thickness)

We develop membrane models for different length scales. The solvent effect is treated as an effective potential between amphiphilic molecules. Hydrodynamic interactions can be taken into account by combining it with a mesoscopic solvent technique. These models are well suitable to study the membrane dynamics with topological changes such as membrane fusion and octopus-like micelle formation (poster)

2. Vesicles in flows

Vesicles and red blood cells show many interesting dynamics in flows We found several shape transitions in the simple shear flow and capillary flow. (poster)

3. Membrane Tubulation by Banana-Shaped Proteins

Local membrane bending by banana-shaped protiens induces shape transformation of membranes coupled with protein self-assembly. (poster)
