Research Interests

Research interests include:-Electric field biomedical treatments: research focuses on applications of electroporation and dielectrophoreisis. Electroporation is a term that is used for the observed increase in permeability of biological membranes to macromolecules through application of high magnitude electric field pulses. The increased membrane permeability allows the transport of material across the membrane that would otherwise be blocked. This effect has significant applications in research including genetic engineering, gene therapy, cancer chemotherapy and cloning. Dielectrophoresis is defined as medium magnitude AC non-linear electric field induced movement of cells. The movement can be used to separate mixed cell types, transport cells from place to place, and arrange cells into structures. This effect has applications in disease diagnosis, immunology, cell characterisation, and cloning.-Power electronics applications: research is primarily involved with the design and construction of high voltage power electronics. Of particular interest are high voltage electronics associated with electroporation research, and small-scale electrical power generation using low temperature differential Stirling engines. -Electro-biotechnology: Bio-feedback rehabilitation devices, electrostatic allergen control, electro-surgery, and neural stimulation.
