A major area of my research is concerned with the physicochemical properties and self-assemblies (such as micelles, vesicles etc.) of synthetic surfactants, especially chiral surfactants. With a wide range of techniques available it is natural that we cover a wide range of problems. My group is interested in how the molecular geometry affects the association properties of ionic surfactants and surfactant mixtures in aqueous and saline solutions. This is primarily achieved by the use of surface tension, fluorescence, rheology, static and dynamic light scattering, and electron and optical microscopy. One of the areas my group currently focusing attention on is drug and gene delivery using stimuli-responsive (pH, temperature, etc.) vesicles and hydrogels. Our aim is to prepare stable unilamellar vesicles and hydrogels of amphiphilic molecules that can be used for drug/gene delivery, formulations of health-care products, and water pollution control.Our research activities also include investigation of the physicochemical properties of polymers and polymer/surfactant mixed systems in aqueous solution. Water-soluble polymers constitute an important class of material which finds application in a wide variety of technologies concerned with, for example, the production of controlled-release systems, agrochemicals, adhesives, coatings, enhancers for oil recovery, foodstuffs, rheology modifiers, personal care products, superabsorbents, catalysis, inks and coding systems. In recent years, increasing environmental pressure to utilize safer, "greener"​ working practices has resulted in a dramatic expansion in the use of such water-soluble/dispersible systems in industrial processes. Water-soluble polymers that exhibit "smart" behavior (i.e. which have the ability to change their conformation in response to an external stimulus such as temperature or pH) are of particular interest.
