Professor Brent S. Murray

Profile

Brent Murray is Professor of Food Colloids in the Department, appointed as lecturer in January 1995. Prior to this he spent 3 years in ICI's corporate colloid research group (UK) and 3 years in the Department of Physical Chemistry Colloid Group, at the University of Melbourne.

Responsibilities

  • Head of Food Colloids & Processing Research Group
  • Deputy Director of Soft Matter and Functional Interfaces CDT
  • Programme Manager for BSc and MSc Food Science

Research interests

Brent's principal research interests are as follows:

  • Particle-stabilized foams and emulsions
  • Protein and polysaccharide microgel particles
  • Biopolymer complex formation as a route to novel encapsulation, emulsification and controlled delivery of functional food ingredients
  • Measurements of interfacial rheology and interfacial phase behaviour of adsorbed biopolymer/biosurfactant films in relation to emulsion and foam formation and stability, including use of Brewster angle microscopy
  • Development of methods for measuring the adsorption/desorption and conformation of biopolymers/biosurfactants at oil-water and air-water interfaces, such as Langmuir trough methods
  • Applications of confocal microscopy, bulk rheology and particle tracking techniques to understand the relationship between colloidal microstructure and bulk texture
  • Measurement of colloidal interaction forces between particles, e.g., emulsion droplets, via atomic force microscopy (AFM) and particle collision techniques, to enable predictions of emulsion rheology and stability, etc
  • Non-food uses of food materials in colloid and surface science technology

The laboratory is equipped for this work with various specialist pieces of equipment including: interfacial rheometers, surface tension apparatus, Langmuir troughs, Brewster angle microscope, atomic force microscope (AFM), confocal laser scanning microscope, controlled stress rheometers, specialized bubble-forming rigs and pressure drop apparatus for foam stability measurements, excellent computing facilities.

This work has been sponsored by UK research councils, EU funding and in collaboration with a number of large national and international food companies. Post-doctoral fellows are very welcome to discuss related projects, funded for example via , UK Research Councils (BBSRC and EPSRC) the European Union (e.g., EU Marie Curie schemes) or the Royal Society, etc.
