My principal research interest is in surface chemistry, materials, polymers, and colloids and also in developing and understanding the correlations between the structures adopted by surfactants/polymeric surfactants at interfaces and the physical properties of these materials in solutions. Such materials have an extensive range of applications and are widely used from enhanced oil recovery (EOR) and personal care formulations through to drug delivery vehicles.

My current work in the Energy Safety Research Institute (ESRI) is focused mainly on material chemistry, functionalisation/synthesis of nanoparticles and microparticles.

  • EG-168 Engineering Professional Development

    To develop fundamental engineering communication skills using standard ICT tools. These skills will be taught and developed in the context of the Swansea Tidal Lagoon. This module also introduces ethics in engineering and continuing professional development.

  • EGA119 Engineering Skills for Aerospace Engineers

    The module will introduce students to a range of professional skills that are part of engineering practice such as group work, ethics, sustainability, health & safety and employability. Technical communication and report writing will also be introduced in the module in the context of the Bloodhound SSC. To allow students to practice these skills a statistical based analysis exercise using Excel will be undertaken. Excel, uncertainty and statistical skills will also be taught as part of the module to support the analysis exercise.

  • EGDM01 Colloid and Interface Science

    Students will gain an in-depth understanding of the properties of colloids and their importance in industry.
