Previously, he worked as software engineer among physicists at CERN on real-time and embedded software for the Large Hadron Collider, as well as data layout abstractions for heterogeneous architectures, for which he received a PhD in High Performance Computing from the University of Dresden, Germany. Before, he implemented GPU accelerated simulations and 3D visualizations of industrial machining processes. Since 2022, Bernhard is a voting member of WG21 and his interests span geometry, 3D visualizations, optimization, SIMD, GPU computing, refactoring and teaching C++. Koen is an engineer specializing in high-quality software with a strong mathematical foundation. With a PhD in Computer Science from KU Leuven, his work bridges applied mathematics and performance-critical software engineering. As Team Lead for HMI Software at NV Michel Van de Wiele, he focuses on developing C++/Qt applications for textile production systems, optimizing performance, usability, and cloud integration. Passionate about elegant, efficient solutions, Koen brings deep expertise in numerical methods, system optimization, and software architecture.

Episode 260: 🇳🇱 C++ Under the Sea 🇳🇱 Ray, Paul, Parrot & Scanman!In this episode, Conor and Bryce record live from C++ Under the Sea! We interview Ray and Paul from NVIDIA, talk about Parrot, scans and more!

Studied Software Engineering at the University of Amsterdam. Founded the Dutch C++ Meetup in 2013 and co-organizes C++ Under the Sea since 2023. He has been programming for more than 25 years, his journey began on his father's Panasonic CF-2700 MSX--and has been hooked ever since. He is also 'the listener' of ADSP the podcast. Paul Grosse-Bley was first introduced to parallel programming with C+MPI at a student exchange to Umeå (Sweden) in 2017 while studying Physics. In the following years he learned more about MPI, OpenMP, OpenACC, Thrust/parSTL and CUDA C++. After finishing his Master's degree in Physics at Heidelberg University (Germany) in 2021, he became a PhD candidate in Computational Science and Engineering researching the acceleration of iterative solvers in sparse linear algebra while being head-tutor for a course on GPU Algorithm Design. He learned using Thrust in 2019 shortly before learning C++ and became enamored with parallel algorithms which led to numerous answers on StackOverflow, contributions on GitHub, his NVIDIA internship in the summer of 2025 and full position starting in February of 2026.
