Background

Jack Wells is the Director of Science for ORNL’s National Center for Computational Sciences, home of the Oak Ridge Leadership Computing Facility (OLCF), a Department of Energy (DOE), Office of Science national user facility, and the Summit supercomputer, located at Oak Ridge National Laboratory (ORNL). Wells is responsible for the scientific outcomes of the OLCF’s user programs. Wells currently serves the American Physical Society as the vice-president of the Division of Computational Physics and serves as vice-president of the OpenACC organization, a user-driven directive-based performance-portable parallel programming model.

Wells has previously lead both ORNL’s Computational Materials Sciences group in the Computer Science and Mathematics Division and the Nanomaterials Theory Institute in the Center for Nanophase Materials Sciences. Prior to joining ORNL as a Wigner Fellow in 1997, Wells was a postdoctoral fellow within the Institute for Theoretical Atomic and Molecular Physics at the Harvard-Smithsonian Center for Astrophysics. Wells has a Ph.D. in physics from Vanderbilt University, and has authored or co-authored over 80 scientific papers and edited 1 book, spanning nanoscience, materials science and engineering, nuclear and atomic physics computational science, applied mathematics, and text-based data analytics.

2019

Vice Chair, Executive Committee, Division of Computational Physics, American Physical Society

As Vice Chair of the Executive Committee, I am in year one of the four-year leadership cycle for APS Division of Computational Physics.

2018

Co-Organizer & Chair, APS Division of Computational Physics (DCOMP) Focus Session at APS March Meeting, (2019) “Building the Bridge to Exascale: Applications and Opportunities for Materials, Chemical, and Biophysical Sciences”.

This focus session will bring together researchers with experience in the effective utilization of high-performance data and compute infrastructure, including supercomputers, communication networks, and data resources to achieve breakthrough scientific results. This includes researchers at experimental facilities such as light and neutron sources with extreme data-science requirements, including machine-learning approaches, and researchers in computational materials, computational chemistry and computational biophysics with experience in large scale simulations. Also of interest software development efforts which will enable novel science on pre-exascale and emerging architectures.

2018

PASC19 Steering Committee

PASC19 is the sixth edition of the PASC Conference series, an international and interdisciplinary platform for the exchange of competences in scientific computing and computational science, with a strong focus on methods, tools, algorithms, application challenges, and novel techniques and usage of high performance computing. The Conference is co-sponsored by the Association for Computing Machinery (ACM) and the PASC structuring project and it is managed by the Swiss National Supercomputing Centre (CSCS).
