I am interested in problems at the interface of mechanics, physics and biology. The mechanics of DNA is one such subject where the Kirchhoff theory of filaments can be used to describe not just the behaviour of DNA at small scales but also its implications on the life cycle of viruses and the switching on and off of genes. Understanding the effects of thermal fluctuations in this context is a major thrust of my research. I am also interested in biological applications of the mechanics of lipid membranes and the mechanics of material interfaces in slender bodies.
