I have a longstanding interest in nanoscience, nanotechnology and nanophysics, condensed or soft-matter self-assemblies and coarse dispersions, including colloidal encapsulation systems and the surface adsorption of functionalising polymers. I study complex formulations such as vaccines, particulate drug delivery systems and nanoencapsulation techniques in considerable depth. I work routinely with biosurfactants (such as proteins and peptides or gums), natural polymers, sustainable materials and synthetically modified materials.
I am interested in recycling and re-exploitation of spent and soiled or spent materials or polluted environments. I am interested in the pollution of water systems and soils by heavy metals, pharmaceuticals and pesticides and by the role micro- and nano-plastic pollution plays in the damage to rivers, coastlines and seas. Work with microplastics (solid bodies) in terms of characterisation of adsorbates and organo-metallic or protein-polysaccharide biofilm fouling and the chemistry of seafoams also feature in my current research. I work with surface active molecules in the form of simple and complex foams and thin liquid films (foam lamellae). These structures relate to the quasi-2D-architectures created for a range of purposes; as means of sensing, synthesis and in their own right, to study processes such as statistical mechanics and energetics. As a nanotechnologist I also work in the field of miniaturised analytical systems – microfluidics, microarrays, sensors, diagnostic systems, and biosensors. I work in the context of product and process design and investigations associated with engineering and manufacturing process modelling. I work with the mechanics and rheology of a range of materials.
I am interested in 'invention' and equipment fabrication and design. I am fascinated by physical and engineering applications of mesophase materials (liquid crystals), coarse and colloidal dispersions, and complex fluids, such as ionic liquids, thermotropic materials, gels and emulsions.
Knowledge Exchange
My interest in knowledge exchange (KE) is manifested in university teaching and research but also in professional body (RSC, RPSGB, IOM3, HEA) and STEM Ambassador work (schools, colleges, university summer schools). Yet more KE is undertaken by industrial consultancy (Smpl Innovations GmbH, Graphic Supplies, Cryolabs, Biofrontera AG, etc), industrially-related academic study (KTPs, KEEP+), pure academic research with chemists, biologists, physicists and engineers at the University of Brighton and the University of Sussex but also more globally (Bulgaria, France, Italy, Sweden, USA, China, India, etc). Even more KE occurs through RCUK grant reviewing activities (EPSRC, MRC, BBSRC), editorial board and editorships (CDDT, Current Nanomedicine) for scientific periodicals, publisher book reviewing (HEA, Elsevier, Wiley) and in text book writing for three fully-authored books (Wiley-Blackwell).
