Name: Pablo Seleson
Pronouns: he/him/his

Biography:
Dr. Pablo Seleson is a Research Scientist in the Multiscale Methods and Dynamics Group of the Mathematics in Computation Section at the Oak Ridge National Laboratory (ORNL). He joined ORNL as an Alston S. Householder Fellow in the Computer Science and Mathematics Division. Dr. Seleson received a BS in Physics and in Philosophy and an MS in Physics, both from the Hebrew University of Jerusalem in 2002 and 2006, respectively, and a Ph.D. in Computational Science from Florida State University in 2010. After graduation, he joined the Oden Institute for Computational Engineering and Sciences at The University of Texas at Austin as an Institute for Computational Engineering and Sciences Postdoctoral Fellow, where he also worked in close collaboration with the Computer Science Research Institute at Sandia National Laboratories. Dr. Seleson’s main research focuses on computational mechanics, specifically peridynamics fracture modeling and simulation, from model development, analysis, and implementation to software development and computational experiments for fracture mechanics applications. His research incorporates multiscale and nonlocal modeling and has more recently broadened to include data-driven surrogate modeling.

Brief Abstract:
Computational fracture modeling is an ongoing challenge in computational science and engineering. Peridynamics is a nonlocal reformulation of classical continuum mechanics designed to simulate fractures thus making it an attractive framework for modeling material failure and damage across many application domains. This has been reflected in an exponential growth in the number of peridynamics researchers and publications worldwide over the last two decades. We have developed at Oak Ridge National Laboratory (ORNL) an exascale-capable, GPU-enabled, and performance-portable peridynamics code, CabanaPD (https://github.com/ORNL/CabanaPD). CabanaPD has been tested on the Oak Ridge Leadership Computing Facility (OLCF) leadership-class computing resources, Summit and Frontier supercomputers, and is built on two main libraries: Kokkos and Cabana, both developed through the Exascale Computing Project (ECP). This project will develop mathematical and computational methods to advance the state of the art of peridynamics modeling and simulation, with the end goal of enhancing current features of the peridynamics CabanaPD code.

Desired relevant skills, background, or interests:
