My broad areas of interest are biophysics and soft-matter physics. I do theoretical studies to understand various physical and biological phenomena, using a variety of tools from physics including equilibrium and non-equilibrium statistical mechanics, polymer physics, and soft-matter theory. I tackle research problems using a combination of computational (numerical) and analytical methods. My specific areas of interest include: (i) Organisation of Chromatin, (ii) Self-assembly of proteins, and (iii) Decision-making in cellular processes.
