Research Interests
Assembly of polymer and particle-based nanostructures; mechanics and instabilities of soft active materials.
Active polymer materials and interfaces
Our group works on a variety of projects related to soft and stimulus-responsive polymer films that can be dynamically reconfigured to change their structures and properties. We take advantage of mechanical instabilities and patterned growth as mechanisms to drive structural transformations.
Self assembly of polymers and particles
We study questions related to assembly of polymers and particles in a variety of contexts including emulsion processing, solution-state crystallization-driven assembly, and melt-state organization in nanocomposites. Our primary interests lie in developing approaches to tailor nanoscale structure for materials with applications ranging from encapsulation and delivery to renewable energy.
