My research is an interdisciplinary work focused on microencapsulation technologies based on the use of natural oils, natural surfactants as well as molecules and materials of natural origin. A particular emphasis is on novel materials obtained by basic chemistry of self-assembly of cyclodextrin molecules at fluid interfaces in relation to application in surfactant free emulsions, foams, microcapsules and colloidosomes.

Techniques used include; surface and interface tension measurements, optical microscopy, fluorescence and electron microscopy, laser diffraction and zeta potential
