Leading scientist



Curriculum Vitae and tasks

My research focuses on the design, the construction and the operation of modern accelerators. In my career I have worked on many of the leading projects in accelerator science, both in operation and in design. I have participated to the following facilities that were constructed and operated: the Large Electron Positron Collider (LEP1 and LEP2) at CERN, the Stanford Linear Collider (SLC) at SLAC, the B-factory (PEP-2) at SLAC and the Large Hadron Collider (LHC) at CERN.

As Leading Scientist (W3) at DESY I am responsible for reinforcing and guiding room-temperature accelerator research in the DESY accelerator division and beyond.

Membership in scientific societies:

  • German Physical Society (DPG)
  • American Physical Society (APS)
  • European Physical Society (EPS)

Curriculum Vitae and tasks

Having finished my PhD on the compensation of long-range beam-beam interaction at the CERN LHC, I joined the MedAustron project, a synchrotron based cancer therapy center, where I was responsible for the beam optics as well as the overall coordination of the technical development of the particle accelerator. Now at DESY, I'm in charge with the project coordination of the upcoming SINBAD ("Short and INnovative Bunches and Accelerators at Desy) facility. I'm thus dealing with conventional accelerators as well as advanced acceleration methods (plasma, dielectrics).

Curriculum Vitae and tasks

My research activity focuses on beam dynamics studies of e-bunches produced and compressed in a linear accelerator for different purposes (e.g. FEL, coherent radiation production, plasma wake-field acceleration). In my career I had the chance to collaborate or directly participate to experiments at different facilities: SPARC at Laboratori Nazionali di Frascati INFN (Italy), PITZ at DESY Zeuthen site (Germany), BESSY II in Berlin (Germany). My work covers theoretical studies by mean of simulating codes but I have also machine shifts and data analysis experience.
I am the primary investigator of ARES (Accelerator Research Experiment at SINBAD).
