In the Complex Fluids and Biological Physics group the researchers are interested in understanding the structure and dynamics of soft and biological materials through theoretical modeling and computer simulations. Primary interest of the group is in non-equilibrium steady state properties of these materials.
The major focus areas of the group currently are in a) morphology of biological membranes b) chromatin structure and dynamics, c) active polymers and d) structural changes of polymer films on external stimulation.
Some of the topics that the group is actively working on are,
- Reversible shape morphism of Vapour-responsive polymer films.
- Multiscale modelling of chromatin assembly and dynamics.
- Tumbling dynamics of single active polymer in shear flow.
- Active membrane recycling induced morphology changes in vesicles.
- Polymer models for Chromatin organization.
