Dr. Allen C. Robinson is a distinguished member of the technical staff at Sandia National Laboratories. Since starting work at Sandia in 1983 his interests have included shaped charge modeling and subsonic jet flow, Rayleigh-Taylor instability in solids and parallel computing for shock physics modeling. He has made major contributions to the development of algorithms associated with ALEGRA, an arbitrary Lagrangian-Eulerian multi-physics simulation code, in particular relative to electromechanical and magnetohydrodynamic modeling, and is currently the technical lead for the ALEGRA project at Sandia. Current interests include the characterization and propagation of uncertainty in multi-scale predictive modeling, structure preserving discretizations and next generation multiphysics modeling algorithms and software implementations.
