My research efforts cover a wide range of fields, and focus on both pure and applied research in the broad areas of colloid and surface science, elasticity, electromagnetic wave theory, rheology, fibre optics, electrostatics, fluid mechanics, granular mechanics, plasticity, atomic force microscopy and nanoscience. This stems from my multidisciplinary background as a trained electrical engineer and subsequent research focus in continuum mechanics.

I am particularly interested in investigating problems of practical relevance, and work closely with leading local and internationally based experimentalists. As such, much of my work is conducted in parallel to experimental measurements, which enables the validity and practical relevance of the models to be verified. This approach has led to the commercial implementation of my work on the international market.

A sample of my recent research efforts include development of models for the dynamic response of nanoparticles under femtosecond laser excitation, failure of plastic materials under gravity, investigation of fundamental properties of atomic force microscope cantilevers and developments of experimental methods for their calibration, and models for the dynamic behaviour of elastic beams immersed in fluids.
