I am researcher at the National Research Council of Argentina (CONICET) in the field of Atomic Collisions and Professor of Quantum Mechanics at the Universidad Nacional de Rosario (UNR). I obtained my PhD in Physics at the National University of Rosario (Argentina) in 1994. I entered the research career of CONICET in 1997. I worked at the Université de Metz (nowadays Université de Lorrane) in France (1995-2001) and Universidad Autónoma de Madrid in Spain (2002-2005) as invited Professor and researcher. I belong to the National Physics Association of Argentina and I am associate member by Argentina of the Commission on Atomic, Molecular, and Optical Physics (C15) of the International Union of Pure and Applied Physics. I am editor of the argentine scientific journal Papers in Physics and I am member of the International Advisory Committee of the International Symposium of Ion-Atom Collisions (ISIAC). My field of theoretical research includes positron impact on atoms and molecules, (e,2e) reactions, fast ion impact on atomic and molecular targets, basic reactions involving molecules of biological interest, two-center interferences in electron emission from molecules, photoionization and interaction of attopulses with atomic and molecular systems.
