I'm an experimental particle physicist. I am a Senior Staff Scientist at the University of Bern (LHEP), an Associate Scientist at the CERN Quantum Technology Initiative and Quantum Computing Advisor to the Open Quantum Institute.
After a decade of precision Higgs and electroweak measurements and detector upgrades with CMS, I now work on what limits those measurements: how much of each particle shower a detector can record, and how efficiently we can compute the predictions we compare with. That is why I lead chromatic calorimetry with quantum-dot materials and a set of quantum-computing projects for HEP.
Higgs, VBF and multiboson measurements with CMS (2014–2025); I led the Mono-Z dark-matter search and the CMS-CSC electronics upgrade, after highly granular calorimetry with CALICE.
Result: CMS Mono-Z search on the full Run 2 dataset, setting a 29% upper limit on invisible Higgs decays at 95% CL. Eur. Phys. J. C 81 (2021) 13
Encoding shower depth in the colour of scintillation light. The concept is validated with layered scintillators; quantum-dot nanocomposite modules are the current development step.
Result: layered-scintillator beam test with electrons and pions up to 100 GeV, showing particle discrimination and longitudinal shower measurement. JINST 20 (2025) P06019
Reformulating HEP bottlenecks for quantum hardware: scattering amplitudes for EFT constraints, QCD splitting functions, real-time hadronisation and generative models.
Result: helicity amplitudes for e⁺e⁻ → ℓ⁺ℓ⁻ evaluated coherently on a quantum circuit and fitted to precision collider data. arXiv:2602.21311

Imagine sitting amidst the stunning backdrop of the Alps, where the world's brightest minds in particle physics convene. That's exactly what happened at the Les Houches 2019 workshop. I will be diving, in this post, into one of the topics discussed there: the Higgs boson's CP properties and a proposal to extend the definition of the Simplified Template Cross Section framework to include CP sensitive bins.
