\r\n
\r\nHe has worked in the Radiation Laboratory of CEPROCOR since 1995. He also teaches at the Faculty of Mathematics, Astronomy and Physics (FAMAF) at the University of C\u00f3rdoba since 1978 and is Member of the Scientific Research Career of CONICET of Argentina.
\r\n
\r\nDuring the period 1988-1992 he was Vice-Dean of the Faculty.
\r\n
\r\nAfter obtaining his M.Sc. in Physics (1978) and his PhD in Physics from the University of C\u00f3rdoba (1985), Professor Rubio became a researcher in atomic and nuclear spectroscopy, with international research activities in Brazil and Italy, being responsible for developing research projects for Argentina in the Frascati and Campinas synchrotron laboratories.
\r\n
\r\nHe developed postdoctoral activities at the University of Rome \"La Sapienza\" in Medical Physics, later serving as President of the Medical Physics Society of Argentina in 1991-1993. His research progressed from fundamental parameters applied to XRF spectroscopy, to diagnostic radiology, characterization of biopolymers by SR \u03bcXRF and X-ray microtomography.
\r\n
\r\nDr. Rubio is author of 50 scientific publications in international journals and more than 60 scientific papers published as proceedings of international conferences, prospective studies from Latin America or virtual items. He is the author or coauthor of six book chapters on XRF subjects and scientific opinion.
\r\n
\r\nIn the field of science policy activities, Dr. Rubio was Secretary of State for Science and Technology of the Province of C\u00f3rdoba (1995-1999) and Director of the Scientific Advisory Council of the National Government (2000-2001).
\r\n
\r\nIn 2008 he served on the National Government as President of the National Funding Agency of Argentina, and since 2009, Dr. Rubio returns to his research and academic activities.
\r\n
\r\nDr. Rubio was one of the founders of CEPROCOR and manager of the \u03bcSat VICTOR project launched successfully in 1996 as the first microsatellite of Argentina.","cvlink":"https:\/\/www.researchgate.net\/profile\/Marcelo_Rubio2","picture":"http:\/\/sarx2016.nbcgib.uesc.br\/speaker\/3\/picture","email":"mrubiocba@yahoo.com","cvfile":null,"created_at":"-0001-11-30 00:00:00","updated_at":"2016-09-16 10:48:11","lecture":"APPLICATION OF SR \u03bcXRF TO EVALUATE THE EFFICACY OF PB SOIL EXTRACTION OF DIVERSE PLANT SPECIES","abstract":"Phytoextraction technologies use plants to extract toxic metals from contaminated soils and accumulate them in the harvestable parts of the plants, which can then be removed from site.
