Research Focus

My broad research interest lies in the physics of soft matter systems. The realm of soft matter comprises of a multitude of systems with important technological applications, with model examples ranging from colloidal suspensions, polymer gels and solutions, granular media to more complex systems of biological matter. Soft matter systems are characterized by the large length and time scales (compared to microscopic lengths) and the thermal fluctuations governing the dynamics of the constituent macromolecules. A wide range of collective phenomena resulting in complex structure and dynamics emerge at such mesoscopic length scales. The recent advancement in experimental techniques have allowed for characterization of such collective behaviors and also provide us with remarkable control down to single particle level. Particle chemistry has succeeded in producing colloidal particle with a definite control over its shape, size and interactions, such as patchy colloids of different shapes. While theoretical formulations of such emergent phenomena rely on the formulations of statistical mechanics out of equilibrium, a more microscopic insight can be gained using computer simulations, bridging the gap between theory and experiments. They serve as an indispensable tool to validate theoretical predictions and gain access to phenomena which are otherwise difficult to observe or measure in experiments. My own research activities strongly build on large-scale coarse-grained simulations of soft matter systems, with a goal to understand the rich physics at such mesoscopic length scales.
