Research Overview

The group’s general interest centers around colloidal particles composed of stimuli-sensitive polymers. From that focus, the goals of the various projects take us in varied directions, depending on the interests and talents of the specific students involved. The areas in which we work can be broadly classified as:

The Chemistry and Physics of Microgel Assemblies


The Chemistry and Physics of Discrete Microgels 

These areas beg the question – “what is a microgel?”. To put it succinctly, microgels are polymer networks (meshes) that are swollen in a solvent; we typically work with water-swellable microgels (hydrogel microparticles). Our challenges are to obtain a detailed understanding of how to make advanced hydrogel particle architectures, how to use such particles in specific applications, and to understand the complex physics of these materials. Work in the group tends to be highly collaborative and interdisciplinary, with collaborations existing between our group and other groups in departments of Biology, Chemical Engineering, Physics, Mechanical Engineering, Biomedical Engineering, as well as Medical Schools. Specific projects of current interest are:

▪       self-healing films

▪       defect tolerant assemblies

▪       bio/synthetic composite matrices

▪       core/shell structures for controlled release
