My broad area of research is equilibrium and nonequilibrium statistical mechanics. In recent years my research has focussed on statistical mechanics of semiflexible polymers with a view to understanding the role of elasticity of biopolymers in, for instance, packaging of DNA molecules in the cell nucleus. Single molecule experiments on biopolymers provides a natural context for such studies. Some of my recent research interest has been in the area of interferometric effects in classical and quantum optics with a view to understanding issues related to classical and quantum information theory.
