Scientific affiliations

I am researcher of CQE - Centro de Quimica Estrutural (CQE) and, currently, the coordinator of the NanoLab - The Nanostructured Materials and Nanotechnologies Laboratory of IST. My areas of scientific interest are centered on the advanced characterization of engineering materials and systems for tribological and biomedical applications, by using Atomic Force Microscopy based techniques.
