B.Sc. in Physics and Materials Engineering (1992; FCT/UNL). Ph.D. in Materials Science – Crystalchemistry and Structural Analysis of petreous and ceramic materials from cultural heritage of the Mediterranean region (contributions for strategies in conservation) using synchrotron radiation (2006, FCT/UNL). Main scientific research activity is focused on structural analysis and crystal chemistry of materials using X-ray diffraction, X-ray fluorescence, differential thermal analysis and thermogravimetry, synchrotron radiation X-ray Absorption Near Edge Structure (XANES) and Extended X-ray Absorption Fine Structure (EXAFS) using large scale installations such as the ESRF (European Synchrotron Radiation Facility). Experimental studies include cultural heritage materials, glass and ceramic materials, mortars, stone and minerals.
