Interest Areas

We are interested in the equilibrium and dynamic properties of polymeric systems that undergo self-assembly at pertinent length scales ranging from nanometers to microns. A number of systems belong to this generic class of materials; thanks to an unprecedented series of advances in polymer chemistry over the past decade, the associated parameter space continues to grow beyond what we are currently able to comprehend. A particular focus of our research will be the identification of the guiding principles in systems that feature multiple self-assembly processes.
