I am particularly interested in interdisciplinary research concerning the development and use of analytical approaches based on scanning transmission electron microscopy (STEM) and Electron Energy-Loss Spectroscopy (EELS). These approaches are applied for the structural and chemical characterization at the sub-nanometer scale of biomaterials, nanomaterials, biological and medical systems. My current interest includes the investigation of the physico-chemical properties of synthetic and natural hybrid organic-inorganic materials to elucidate their properties and formation mechanisms. Part of my work is dedicated to the study of biominerals (shells, bones, pathological calcifications).
