Scientific Interests

Electrochemistry, surface (bio)functionalization, including nanomaterials, with organic coatings (self-assembled monolayers, biomimetic supported lipid membranes, adhesive polymers, metalloporphyrins, biomolecules) for biosensing and electrocatalysis. Expert on high resolution imaging (from atoms to bacteria, using scanning tunnelling and atomic force microscopy), electrochemical and optical characterization techniques (e.g. ellipsometry and surface plasmon resonance).
