The focus of our research is the application of in situ optical techniques, particularly infrared spectroscopy, to study adsorption processes and reactions at metal electrode surfaces. Of current interest is the effect of the electric field on the conformation adopted by phospholipid bilayers assembled on electrode surfaces and their interaction with peptides.
Our interests also include modification of surfaces with organic molecules and/or metal nanoparticles, and electrocatalysis. Classical electrochemical methodology is combined with modern in situ techniques to determine structure of our tailored surfaces and catalysts as well as reaction mechanisms. The underlying theme of our work is to understand interfacial processes at a fundamental level, with a view toward exploiting this information in the development of new materials, sensors or catalysts
