At Complex Fluids and Biological Physics group the researchers are interested in understanding the structure and dynamics of soft and biological materials through theoretical modelling and computer simulations. Primary interest of the group is in non-equilibrium steady state properties of these materials.<\/p>

As a part of CSBM our work is focused on understanding of the chromatin organization, shapes of biological membranes and cytoskeletal organization.\u00a0\u00a0 We believe these studies are of importance in understanding the physics of structure and organization of biological systems. We have proposed a novel polymer model for chromatin that include the effects of structure modifying chemical reactions.\u00a0 We have developed a variety of powerful simulation techniques to study the dynamics of multi-component fluid membranes and membranes with protein like inclusions.\u00a0 We are also interested in the interplay of cytoskeleton tension and membrane elasticity.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\tWith the aim to understand the physical mechanisms leading to convoluted shapes of\u00a0 cellular organelles, we investigate the\u00a0 steady state shapes of vesicle subjected to active fission and fusion from the outer surface.\u00a0 Our study on active polymers, that are semi flexible elastic filaments immersed in a viscous fluid with energy converting \u201cactive\u201d elements distributed along its length, is aimed at modeling cytoskeletal filaments.\u00a0\u00a0 In the past we have also looked into\u00a0 a 3D model with elastic filaments and molecular motors to study the response of cytoskeleton mimicking networks to external forces and\u00a0 pattern formation in mixtures of molecular motors and microtubules.
