The physics of particle accelerators, particularly the design and performance of circular colliders, formerly Senior Physicist at CERN. As a CERN staff member from 1980 to 2019, I was responsible for the heavy ion beams in the LHC from 2003 to 2019, colliding lead nuclei with each other and with protons. Earlier, I worked on both LEP and LHC colliders from their early design phases. I supervised a number of PhD and other students for various European universities. Since January 2020, I have joined the ALICE experiment at the LHC, affiliated with GSI, Darmstadt, but I continue to be based at CERN. Some past community service activities: Director, Joint Universities Accelerator School, 2021. US National Academies, U.S.-Based Electron Ion Collider Science Assessment 2018, High Energy Particle Physics Board, European Physical Society (2012-19) CERN Senior Staff Advisory Committee ("The Nine") 2017-19 Chair, Collider-Accelerator Department, Machine Advisory Committee, Brookhaven National Laboratory, NY, USA (2014-15) Scientific Committee, INFN Laboratori Nazionale di Frascati (2006 to 2012) Chair, ICFA Beam Dynamics Panel (2002-5) NSAC Review of U.S. Program in Heavy Ion Nuclear Physics (2004). CERN Scientific Information Policy Board Editorial Board of Physical Review STAB (now AB), 2005-2007 Organised 1st Joint US/CERN Accelerator School, 1985 Lectured at various Accelerator Schools in Europe and USA Although not a computing "professional", I can claim to have had some influence on software used in our community: I was one of the original team to specify the requirements of the MAD (now MAD-X) accelerator physics program. I introduced LaTeX to CERN in 1986. That was a struggle. I pioneered the use of "computer algebra" in accelerator physics, first with Macsyma on a Symbolics Lisp Machine in the 1980s, then REDUCE, finally Mathematica, which I now use as a universal tool for many computational purposes, including as a way to extend interaction with MAD.
