Ricardo Lebensohn completed his Ph.D. in Physics in University of Rosario, Argentina, in 1993. After being a postdoc in the Polytechnic Institute of Grenoble, France, he returned to Argentina as professor and researcher of the National Research Council at the Physics Institute of Rosario. In 2003 he joined Los Alamos National Laboratory, where he is presently a senior scientist of the Materials Science and Technology Division, working in the area of modeling the structure/property relationship of crystalline materials. His contributions include the development of the ViscoPlastic Self-Consistent (VPSC) formulation and code. VPSC is a formulation based on non-linear homogenization for the prediction of texture evolution and texture-induced anisotropy of polycrystalline materials. The VPSC code is presently used for parameter identification, interpretation of experimental results and in multiscale calculations by numerous R&D groups worldwide. Dr. Lebensohn has also developed a spectral method for the prediction of full micromechanical fields in deformed polycrystals, using direct input from images of their microstructure. This efficient simulation tool is an ideal complement to emerging three-dimensional characterization techniques in experimental mechanics. Dr. Lebensohn recently received the Humboldt Research Award for "pioneering work in the field of multiscale modelling of plasticity of crystalline materials" and is a member of the editorial board of International Journal of Plasticity.
