    Esteban

    Esteban Rougier obtained his Doctorate on Computational Mechanics of Discontinua from Queen Mary and Westfield College, University of London (London, UK). Previously he obtained a BS degree on Aeronautical Engineering from the Universidad Catolica de Cordoba (Cordoba, Argentina) and another BS degree from the Instituto Universitario Aeronautico (Cordoba, Argentina).

    His research efforts during his PhD studies were concentrated on the Discrete Element Method (DEM) and its applications to micro and nano-scale systems. Later on Dr. Rougier extended his research interests to the study, implementation and testing of different algorithmic solutions for the Combined Finite Discrete Element Method (FDEM).

    Since his arrival at LANL, Dr. Rougier has specialized on the area of development and implementation of FDEM algorithms, fluid-solid interaction solvers, material models for high and low strain rate processes (for geomaterials and brittle metals) and on applying the FDEM method to a number of different applications, such as hyper velocity impacts, earth material characterization, weapons effects studies, earthquake rupture modeling, hydraulic fracturing, underground nuclear explosion containment and the study of bolide impacts, among others.
