Our research group works to develop new methods to characterize the microstructure of materials at the nanometer resolution with state of the art electron microscopes. The chemical composition, the crystalline structure and the morphology are characterized an the nanoscale with innovative computer programs that process electron microscope data into quantitative information. The Monte Carlo simulation programs of electron trajectories that we have developed in the last 2 decades are world famous in this regard. Our quantitative electron microscopy applies to advanced metallic alloys, ceramics, polymers,  nanomaterials, minerals, bio materials, cells and any other materials.
