  • I'm interested in fluids that don't behave like the standard (air, water, honey) Newtonian model. This field has wide-ranging industrial applications - including plastics manufacture and the processing of toothpaste. I work on a variety of flow scenarios including particles suspended in a viscous fluid (for example, with my recent Ph.D. student Adam Townsend below and my current postdoc Jurriaan Gillissen); polymeric liquids (for instance, with my first Ph.D. student Sally Everitt); instabilities in elastic liquids (including work with my recent Ph.D. student Hugo Castillo Sanchez and a collaboration with Suzanne Fielding at Durham on shear-banding instabilities), and the doubly-complex question of particles suspended in a viscoelastic fluid with current Ph.D. student Liam Escott.
  • Recent or current funded projects include:
    • Shear-thickening fluids for cryopreservation in which we began an exploration of whether interactions between particles in suspension could inhibit the growth of ice crystals. This work was led by Asymptote and funded by Innovate UK.
    • Complex ORAL health products (CORAL): Characterisation, modelling and manufacturing challenges. Here we are working with UCL Engineers and commercial sponsor GSK to investigate the rheology of three-phase suspensions in a viscoelastic matrix, with application to toothpastes. This work is funded by EPSRC.
    • Extensional Rheology Matters, a small project funded by EPSRC in which I aimed to develop tools to assess whether extensional flow components are important in a given flow situation.
