My interests lie in theoretical soft materials physics and biophysics. My current research focuses on two fundamental aspects of polymeric materials: the formation of nanostructures in polymeric materials via self-assembly, and the interplay between these structures and the dynamical evolution of the polymeric material. Self-assembled macromolecular aggregates find applications as, for example, nanolithographic templates, paints, adhesives and drug delivery vehicles, and also form important structural elements in cells. The study of the structure, dynamics and response of biological assemblies is also a research theme in my group. We use a combination of sophisticated analytical theory and high-performance computation to model the behaviour of these systems.
