My research is at the interface between nanotechnology, biomedicine, and energy; it involves the application of materials science, physical chemistry, surface thermodynamics, solid state physics, biochemistry and molecular cell biology to energy, biomedical and chemical engineering systems. At the centre are studies of the molecular self-assembly and interfacial phenomena in multiphase systems where nanomaterials or molecules in different states (or phases) co-exist and interact with one another. The current effort is to design and measure the molecular interaction, nanostructure formation and adsorption kinetics of peptides, DNA, RNA (siRNA), proteins, surfactants, polymers, metals and inorganic compounds in solution or at interfaces. The research applies techniques emerging from innovations in nanotechnology, genomics, proteomics and nano/microelectronics to problems in nanomedicine, colloid and surface science, and alternative energy. Practical applications include drug and gene delivery; peptide-DNA/RNA binding; protein-lipid interactions, lipid bilayer and cell membrane actions; therapeutic lung surfactants; emulsification, coating, painting, and thin films; surface mass and heat transfer; molecular/microsensors; nanotube membranes and bioseparation; energy storage and conversion. The study is highly interdisciplinary and can involve both experimental and theoretical work. The integrated research approach is having significant impact on the success of many emerging energy, biomedical and chemical technologies; it is an exciting and rewarding area of study for PhD and MASc students with a background in chemical engineering, mechanical engineering, materials science, physics, chemistry, mathematics or biology.
