Short CV

Professor Ortiz received a BS degree in Civil Engineering from the Polytechnic University of Madrid, Spain, and MS and Ph.D. degrees in Civil Engineering from the University of California at Berkeley. From 1984-1995 he held a faculty position in the Division of Engineering of Brown University, where he carried out research activities in the fields of mechanics of materials and computational solid mechanics. He is currently the Dotty and Dick Hayman Professor of Aeronautics and Mechanical Engineering at the California Institute of Technology, where he has been in the faculty since 1995 and currently serves as the director of Caltech’s DoE/PSAAP Center on High-Energy Density Dynamics of Materials. Professor Ortiz has been a Fulbright Scholar, a Sherman Fairchild Distinguished Scholar at Caltech, Midwest and Southwest Mechanics Seminar Series Distinguished Speaker, a Fellow and an elected member-at large of the US Association for Computational Mechanics, and an elected Fellow of the American Academy of Arts & Sciences. Professor Ortiz has served in the University of California Office of the President Science and Technology Panel and in the Los Alamos National Laboratory T-Division Review Committee. He currently serves in the Lawrence Livermore National Laboratory Predictive Science Panel, the Sandia National Laboratories Engineering Sciences External Review Panel, the Lawrence Livermore National Laboratory Chemistry, Materials, Earth and Life Sciences Directorate Review Committee, the National Research Council Panel for the Evaluation of QMU and he chairs the Lawrence Livermore National Laboratory Engineering Directorate Review Committee.
