Academic Interests

I am a surface chemist with an interdisciplinary background that covers from biomolecular interactions to the development and physicochemical characterization of biocompatible coatings.

My main research interests include: salivary pellicle, dental materials, protein adsorption, bioinspired coatings and biomaterials, and DNA-protein interactions.
