Soft Matter and Biological Physics at Surfaces

We study soft matter and biological physics at surfaces. Soft and biological systems are very sensitive to their environment such that small changes in temperature and pH, as well as the application of external fields, can produce large changes in their properties. This sensitivity can be exploited to tune the properties of the systems and to achieve a deep understanding of the subtle interplay between different interactions. This research also leads naturally to the discovery of new and unique biomaterials, which can be exploited in new technological applications.

We apply a broad range of surface-sensitive experimental techniques and fundamental, physics-based strategies to investigate the fundamental properties and practical applications of biophysical systems and novel biological molecules and materials. We focus our approach on questions such as:

  • What is the nature of the unique interaction of monodisperse polysaccharide nanoparticles with water?

  • What are the effects of the curvature of an interface and changes in the environment on the conformation of surface-bound proteins?

  • What is the effectiveness and mechanism of action of novel antimicrobial compounds?

  • How do bacteria stick to and move across surfaces?

  • How do enzymes break down cellulose so that cellulosic ethanol can be made more efficiently?

  • What are the structure and mechanical properties of naturally occurring, nanostructured biomaterials?

The answers to these questions lead to improvements in understanding as well as new applications and technologies.
