Julien Bigot holds a PhD in computer science and works as a permanent CEA Research Scientist at Maison de la Simulation. His main research interest is related to programming models for HPC applications. He focuses on separation of concerns between performance optimization and semantics, both for algorithm expression and data analytics. He co-leads Exa-DoST, the project of NumPEx building the French data-oriented Exascale software stack. He also leads CExA, the project of the CEA to contribute to Kokkos and port applications to GPU based on this.

Todd Gamblin is a Distinguished Member of Technical Staff at Lawrence Livermore National Laboratory (LLNL). He created Spack (spack.io), a widely used open-source package manager for high performance computing, partially sustained by the PESO project. He is a co-founder of the High Performance Software Foundation (hpsf.io). At LLNL, he works on software and future computing strategy in the Advanced Technology Office in LLNL’s Livermore Computing division, and he leads a number of research and development projects focused on software integration.

Damien Lebrun-Grandié is a Senior Computational Scientist at Oak Ridge National Laboratory with over a decade of experience in the field. He holds a PhD in Nuclear Engineering from Texas A&M University, a MSc in Physics from the Karlsruhe Institute of Technology in Germany, and a MEng in Physics Engineering from Grenoble INP in France. His research focuses on developing algorithms and enabling technologies for solving large-scale, complex engineering, and scientific problems.
As a founding member of the High Performance Software Foundation, Damien was instrumental in getting the organization started and continues to play a leading role on the Governing Board, representing the Technical Advisory Council. He is also the co-lead of the Kokkos C++ performance portability project, where he oversees a large international team of developers and researchers. Additionally, he represents ORNL on the C++ Standards Committee, where he has been a key contributor to foundational features for scientific computing like std::mdspan in C++23 and std::linalg for C++26.

Megan Phinney earned a BS in computer engineering at Iowa State University in 2022. She joined Los Alamos National Laboratory (LANL) in 2020 as an undergrad student and was promoted to staff scientist in 2022. During her time as a student she was awarded the Distinguished Student Performance Award in 2021. At LANL, she works on container runtimes and workflows as a part of the Charliecloud project. She also provides user support for HPC systems. In her free time, she enjoys reading and playing with her pit bull.

Elaine M. Raybourn is a social scientist and Steering Committee Secretary for the Consortium for the Advancement of Scientific Software. Formerly at Sandia National Laboratories, she contributed to the Department of Energy Office of Science Exascale Computing Project (ECP) and Next Generation Scientific Software Technologies stewardship. She earned a Ph.D. in Intercultural Communication with an emphasis in Human Computer Interaction from the University of New Mexico, and certificates in Modeling & Simulation of Behavioral Cybersecurity and Data Ethics from the University of Central Florida and Cornell University, respectively. Elaine was a European Research Consortium for Informatics and Mathematics (ERCIM) Fellow with Fraunhofer FIT in Germany, the French National Institute for Computer Science (INRIA), and BT Global Research and Development in the UK. Her research interests include scientific software teams and HPC AI readiness.
