Andreas Salzburger
Senior Staff at CERN
Geneva, Geneva, Switzerland
Summary
👤
Senior🎓
Top SchoolAndreas Salzburger is a CERN Senior Staff physicist and software architect with over a decade of experience building high-performance particle tracking, simulation, and reconstruction systems for the ATLAS experiment and future colliders. He leads large-scale projects and working groups (including ACTS and HSF reconstruction/trigger efforts), combining hands-on C++ core development—such as Kalman filtering and propagation algorithm improvements in the prominent acts-project—with strategic coordination of detector upgrades and software roadmaps. His work blends experimental physics rigor with machine-learning innovation, exemplified by organizing the Tracking Machine Learning Challenge and publishing progressive ML-based fast simulation methods. Known for refactoring legacy code into modular, experiment-independent toolkits, he brings a rare mix of deep domain expertise, leadership across international collaborations, and a knack for turning complex detector problems into practical, reusable software.

Nov 2015 - Jan 2023
Experiment-independent toolkit for (charged) particle track reconstruction in (high energy) physics experiments implemented in modern C++
Role in this project:
Back-end Developer
Back-end DeveloperContributions:1807 reviews, 1242 commits, 756 PRs in 7 years 3 months
Contributions summary:Andreas primarily worked on back-end related tasks, primarily on the core of the physics experiments. Their commits involved removing legacy extrapolation, adding user surfaces to the Navigator class, implementing the first Kalman filtering sequence, adding material map functionality, refactoring the surface and volume class, and updating the main propagation algorithm. These changes reflect work that would have been needed for improving the internal structure and performance of the particle track reconstruction code.
