Rockstar🎓
Top SchoolFons Rademakers is a project leader at CERN with a PhD in particle physics and more than 25 years designing high-performance data analysis and visualization systems. As co-founder and long-time leader of the ROOT project — the analysis toolchain used across particle physics and central to the LHC Higgs discovery — he has modernized threading, build systems and parallel analysis (PROOF). Early in his career he developed column-wise ntuples and the PIAF parallel analysis system, which was sold to HP for $1M, illustrating a rare blend of research and commercial impact. He served as CERN openlab CTO and Chief Research Officer, brokering industry partnerships and steering R&D and technology transfer. A hands-on open-source contributor to ROOT and the Cling C++ interpreter, he also co-founded BioDynaMo and now leads CERN’s CBACK disaster-recovery backup project, combining low-level engineering with strategic program leadership.
