Pablo Seleson, Ph.D.

Research Scientist

Computer Science and Mathematics Division

I am a Research Scientist in the Multiscale Methods and Dynamics Group of the Mathematics in Computation Section at the Oak Ridge National Laboratory (ORNL). I joined ORNL as an Alston S. Householder Fellow in the Computer Science and Mathematics Division. My research focuses on multiscale materials modeling and on mathematical and computational analysis of peridynamics and related nonlocal models with applications to computational fracture modeling.
