Interview candidate: Mohamad Roumié
Mohamad Roumié received his PhD in Nuclear and Accelerator Physics from Strasbourg University in 1994 and joined the Lebanese CNRS in 1996. He is currently Research Director at the Lebanese Atomic Energy Commission of the Lebanese National Council for Scientific Research (CNRS-L) where he is the head of the unique ion beam accelerator facility in Lebanon. He is a recipient of a Fulbright fellowship and the Lebanese CNRS Research Excellence Award. He is active in many collaboration research projects with local and international partners including American University of Beirut, International Atomic Energy Agency, Arab Atomic Energy Agency, Centre de Recherche et de Restauration des Musées de France, Centre d’Etudes Alexandrines, Italian CNR and French CNRS. His research interests focus on promoting and using Ion Beam Analysis techniques (IBA) for applied research in materials science, environment and cultural heritage. In addition, he was a lecturer at the physics department of the American University of Beirut 2005-2019; supervisor or co-supervisor of more than 20 Master and PhD students; author and co-author of 100 articles in international peer reviewed journals; referee of scientific papers in many international journals and a reviewer of national and regional funded projects.
Development of Accelerator Based Techniques for Applications in Archaeology to Nanotechnology
The accelerator based techniques, such as ion beam analysis IBA, are widely used in different fields of applied research as powerful tools to characterize new materials, geological materials, art and archaeology objects, environmental and biological samples. Proton induced X-ray emission PIXE, proton induced gamma ray emission PIGE and Rutherford backscattering spectroscopy RBS, are based on the use of 1-4 MeV proton or alpha particle beams that are delivered by an electrostatic accelerator machine. Being multi-elemental, fast and sensitive, these techniques can exhibit unique advantages when they are combined together. They can be used either in air mode or under vacuum, with mm or µm beam size, in addition to their scanning imaging and spectroscopic capabilities. Accordingly, some case studies will be shown to highlight the usefulness and the strength of these techniques for multidisciplinary research studies.
