- Research Officer
Thiverny2010 - 2013The Colloids Science and Complex Fluids ECG has expertise in the design and development of complex fluids and ‘soft’ solids which is derived from a deep understanding of the colloid science, rheology and molecular associations involved controlling the properties and performance of a broad range of products. The focus of the group’s work is
the formation, stabilization and characterization of emulsions, dispersions and foams, and controlling the flow behaviour (rheology) of fluidic and soft solid products by formulation to optimize their stability, ease of use and application performance.
