On 1 September 2016, a new Spokesperson and two Deputy Spokespersons took over at the helm of the CMS Collaboration. You can read about the new heads of the CMS management below. For more information, please read New CMS spokesperson: "An honour to be chosen to lead a spectacular collection of people" and A word of thanks from the outgoing CMS management.
Joel Butler, Spokesperson
Joel Butler, senior research scientist at the Fermilab, earned his bachelors degree in physics from Harvard in 1969 and his Ph.D. from MIT in 1975. He has worked on CMS continuously since 2005. In 2005-2007, he led the US effort to complete the forward pixel detector (FPIX). He then became manager of the US CMS Operations Program, consisting of the approximately 50 US institutes with more than 400 Ph.D. physicists and over 200 graduate students. In addition, Joel served as CMS Deputy Upgrade Coordinator from 2008-2012 and superintended the writing of the Phase 1 Technical Proposal. In 2014 and 2015, Joel helped coordinate the Computing, Software and Analysis Challenge (CSA14) in preparation for 13 TeV data-taking and served as one of the editor/writers of the Phase 2 Technical Proposal and Scope Document.
Before joining CMS, Joel held many leadership and management positions in the Fermilab administration and scientific program. He developed a new wideband photon/electron beam and a new photoproduction experiment to study charm particle properties with it. The photon beam was completed successfully in 1985 and two experiments, E687 of which he was co-spokesperson, and E831/FOCUS, took data periodically from 1988 to 1997 and produced many excellent results on charmed-particle spectroscopy and decays. Having worked on early computing clusters for E687, Joel became one of the founders of the Fermilab Computing Division, serving as Division Head from 1994 to 1998. From 1998 to 2000, he participated in the MONARC Project that wrote down the original “tiered” computing model for the LHC experiments and led the successful effort to secure funding for the US CMS Computing Project. Most of Joel's physics research efforts have gone into heavy flavour, i.e. bottom and charm physics, focused on spectroscopy and rare decays.
Günther Dissertori, Deputy Spokesperson
Günther Dissertori studied Physics at the University of Innsbruck, Austria. In 1997 he obtained his PhD in Physics for a thesis on theoretical studies and experimental data analyses related to the ALEPH experiment at LEP. During the following four years he worked at CERN, first as a Research Fellow and then as a Research Staff scientist. During that time, he continued his work on the ALEPH experiment and started his involvement with the CMS detector at the LHC. He has been a member of the CMS Collaboration since 1997. In 2001 he became Assistant Professor at ETH Zurich and since 2007 he is Full Professor. Currently he is the Head of the Institute for Particle Physics. The main focus of his research group was/is the construction, commissioning and operation of CMS, with particular emphasis on the Electromagnetic Calorimeter (ECAL). Since the start of data taking, his group has been strongly involved in the data analysis efforts. He has already carried a significant number of coordination/management roles, such as JetMET POG co-convener, Deputy Physics Coordinator, Chairperson of the ECAL Institution Board and most recently Deputy Chairperson of the Collaboration Board. Besides his research activities, Günther pays particular attention to his teaching at ETH, which has been awarded by three ETH Golden Owls and by the Credit Suisse Award for best teaching at ETH.
Roberto Carlin, Deputy Spokesperson
Roberto Carlin studied Physics at the University of Padova, Italy. In 1989 he received the PhD in Physics with a thesis on the measurement of the electromagnetic for factors of the nucleon with the experiments PS170 at CERN and Fenice at Frascati (Italy), and he is now Full Professor in the Department of Physics and Astronomy of the University of Padova. In 1986 he had started to contribute to the ZEUS experiment at the electron-proton collider HERA at DESY (Hamburg) working on the design, construction and commissioning of the barrel-rear muon detector and of its trigger and data acquisition, later becoming Project Manager of the detector. He then moved to be Trigger Coordinator of the experiment, co-Project Manager for the construction of the new silicon vertex detector and finally Deputy Spokesperson of ZEUS from 2003 to 2005. Roberto then joined the CMS group of Padova, to work on the installation and commissioning of the muon Drift Tube detector and then to coordinate its initial running as Deputy Project Manager. From 2012 to 2015 he has been the Trigger Coordinator of CMS. In Padova Roberto has taught “introduction to particle detector and accelerators”, and presently teaches “physics for engineering”.
