Beam Instrumentation physicist and leader of the Proton Beam Physics and Instrumentation group at Paul Scherrer Institut (PSI). Responsible for beam profile and beam loss monitoring in PSI proton facilities (HIPA and Proscan). On top of my regular responsibilities, my research interests cover accelerators for light ion (particularly He4) radiotherapy, use of carbon-nanotube based materials and application of Machine Learning and Artificial Intelligence in the operation of accelerators.

Past Experience

In the past I have worked:

  • at SEEIIST and TERA foundation as an accelerator physicist, on design of new carbon therapy and helium therapy facilities.
  • at GSI with the following main tasks:
    • operation of accelerator complex (deputy leader)
    • management and development of high-energy beam transfer lines (HEST machine coordinator)
    • machine data analysis, a link between operation and beam instrumentation
  • at CERN with the following main tasks:
    • responsibility for PS, SPS and LHC Ionization Profile Monitors
    • coordination of beam-induced quench tests of LHC magnets at the end of Run I
    • generation and initial setting of Beam Loss Monitor thresholds
    • coordination of development of Cryogenic Beam Loss Monitors
    • simulation of thermal processes for Beam Wire Scanners
  • at INFN/Rome — participated in Dark Matter search in cosmic rays in the antideuteron channel for the AMS experiment.
  • at IN2P3/Montpellier — worked on the AMS detector itself (calorimeter and tracker) and on its capability to measure gamma rays.
  • at IFJ Krakow (and CERN) — worked on physics simulations of low-mass Higgs boson in the ATLAS experiment and beam tests of the TRT detector.

Main Areas of Expertise

Detector physics (ionization chambers, semiconductor detectors, Multi-Channel Plates, etc.), particle shower simulations (Geant4), beam-material interactions (thin targets, beam-induced damage and quenches of superconducting magnets), data analysis (ROOT, Python, Mathematica, machine learning) and accelerator physics (beam optics calculations).
