Spatiotemporal orders in the realm of Chemistry and Biophysics(Theory and Simulation group)
Self-organization leading to spontaneous ordering in living and nonliving systems is ubiquitous and widespread phenomena in nature. This formation of orders structures in the composition of a system may occur in both temporal and spatial domains. The occurrence of temporal orders e.g., oscillation or rhythms are extensively encountered in the field of chemistry and biology. In spatially extended systems when temporal kinetics is coupled through diffusion, the spatiotemporal dynamics become more rich and complex which could generate varieties of spatiotemporal instabilities in the form of stationary and nonstaionary patterns, spirals, targets, traveling, solitary waves etc in far-from-equlibrium condition. The range of such instabilities in living systems are prevailed from single cell to multicellular organizations. Cells in bacterial colony or in tissues collectively organize and coordinate themselves in various ways to perform a particular function. The underlying mechanisms of these processes are themselves very complex and the complexity enhances in the presence of certain physicochemical factors. Our research is broadly focused towards investigating the spatiotemporal dynamics of non-equilibrium complex systems to understand of a number of emerging phenomena of chemical and biophysical interests. We cater interdisciplinary and integrative approaches where tools of nonlinear dynamics, statistical mechanics and computational modeling are used to address various phenomena of self-organization.
Currently, we are interested in the following areas:
- Computational investigation of spatiotemporal dynamics of micro-organisms
- Nonlinear dynamics of chemical oscillatory and reaction-diffusion systems
- Cell motility: Prokaryotic and Eukaryotic
