Education and Professional Experience

  • M.S. and Ph.D., Mechanical Engineering, Stanford University, 1984, 1989
  • B.S. and M.S., Civil Engineering, Case Western Reserve University, 1980, 1981

Dr. Ferencz has pursued computational mechanics R&D since first being an undergraduate structural engineering student, creating meshes by hand and entering data on punch cards. He currently leads LLNL’s Computational Engineering Division. This organization has over160 technical staff with expertise in Engineering Modeling and Simulation, Data Analytics and Decision Science, and Signal and Image Processing. This collection of analytic expertise supports many Laboratory programs, external projects, and research collaborations. Dr. Ferencz has also participated in the private sector, being among the founders of a firm focused on multiphysics simulation software, playing a variety of technical and management roles culminating in Vice President of Engineering. For the past eight years, Dr. Ferencz has been a voting member of the ASME Standards Subcommittee for Verification and Validation in Computational Solid Mechanics.

Research Interests

Computational solid and structural mechanics, particularly global algorithms for nonlinear implicit finite element methods, advanced applications, and verification and validation.
