I am interested in the Equilibrium and Non-Equilibrium properties of Physical systems from a Statis- tical Mechanics perspective. I work in two areas of Statistical Mechanics: (i)Physics of nucleation and crystallization phenomena and (ii)Noise- induced Phenomena (i)Physics of nucleation and crystalliza- tion Phenomena- A topic of fundamental interest in Statistical mechanics of Soft Matter systems is the Physics behind the nucleation and the eventual crystallization of a liquid to a solid. We are interested in how the microscopic interactions between individual particles influence the nucleation process and the underlying phase behavior of a substance. I am actively engaged in investigating this topic through Molecular simulations. (ii)Noise-induced phenomena - Noise, while generally seen as having a destructive effect, can some- times play a constructive role such as in the movement of tiny motors in the nanoscale world, also known as Brownian motors. At these small length scales, classical thermodynamics fails to make any useful prediction and the behavior of such stochastic systems has to be understood in the framework of Stochastic Thermodynamics. In our research group, we apply theoretical approaches from Stochastic methods as well as Computer simulations to investigate such systems. I am also interested in the Statistical Mechanics of other Soft Matter systems such as Self Propelled particles (active matter), Polymer- nanopore systems etc. I have a funded project via the UGCFRP Start-Up Grant on investigating nucleation and crystallization phenomena via molecular simulations. I have a collaboration with University of Duesseldorf in Germany on various topics in Soft Matter Physics
