Ian joined CMS in 2001. He was a Forward Pixel manager coordinating the production of the forward silicon sensor modules by a team of 14 undergraduate and graduate students at Purdue. In 2010 he was the Quarkonia Working Group co-Convener, producing the first measurement of the Upsilon production cross section at the LHC and the eye-catching plot that simultaneously shows many Standard Model particles, from the eta to the Z. In 2011-12 the team, with Heavy Ion colleagues, observed sequential Upsilon suppression in heavy-ion collisions, regarded by many as a smoking gun for the Quark Gluon Plasma. Recently Ian’s group has joined colleagues from RAL and Princeton to search for new physics through the detection of long-lived particles, and is executing the cross-check analysis of B_s→μμ. During 2009-'12 Ian was co-coordinator of the LHC Physics Center (LPC) at FNAL where he co-developed the CMS Data Analysis School (CMSDAS) and the CMS Fellows programme that supports more than 20 post-docs and young faculty annually. He has been ARC Chair for a variety of Higgs, electroweak, beauty and quarkonia analyses.

After a PhD from Edinburgh for studies of CP violation in the kaon system with NA31 at CERN, he joined the CLEO experiment at Cornell. He led the fabrication of the CLEO II muon detection system and the CLEO III SVX, and made precision measurements of V_cb, V_ub, V_cs and V_cd. In 2000 Ian was one of the leaders of a group who proposed and designed a new experiment, CLEO-c, to test Lattice Gauge Theory calculations and search for new physics with charm. He was co-Spokesperson of CLEO III and CLEO-c (2001-04). He is Julian Schwinger Professor at Purdue, a Fellow of the American Physical Society (APS) and the American Association for the Advancement of Science (AAAS). He is currently a member of ICFA, the Board of overseers of FermiLab, The SLAC Policy Committee, the Argonne National Lab Physical Sciences Advisory Group, and the Board of Directors of the Large Synoptic Survey Telescope Corporation. He is the Chair-elect of the APS Division of Particles (DPF) and is co-Chair the DPF Coordinating Panel on Advanced Detectors. He has mentored 12 PhD students and 10 postdoctoral fellows. Ian loves to teach, and has received Purdue’s highest award for teaching and is extensively involved in public outreach, especially for CMS. He is profoundly deaf and has given over sixty colloquia and talks to the public on hearing, cochlear implants and perception since 2003. He is in awe of CMS and his CMS colleagues, his wife Daniela Bortoletto (also on CMS) and his twenty-year old daughter who is training to be a opera singer.

Claudia studied physics at the Vienna University of Technology and started her career at the UA1 experiment in 1982 as a summer student. Later she obtained a CERN fellowship, under the leadership of Carlo Rubbia. Employed by the Institute of High Energy Physics of the Austrian Academy of Sciences, she worked briefly on the electromagnetic calorimeter of the NA48 experiment, before becoming leader of the emerging Austrian CMS group. She contributed to the design of the trigger system. In particular, she proposed new ideas for the Level-1 Global Trigger and initiated the development of the Trigger Supervisor. She has been deputy Trigger Project Manager and Institution Board Chair for TRIDAS. On the physics side she has performed studies for new heavy vector bosons and is participating in searches for supersymmetry and exotica.

Claudia has been a member of most CMS committees. She was Chair of the Conference Committee, Regional Representative for Other CERN Member States in the Management Board, a member of the Authorship Board and the Advisory Board to the Collaboration Board. Currently she is a member of the Publications Committee in the field of exotica, and of the Thesis Award Committee. She also lectures as an Adjunct Professor in Vienna and is the Austrian representative in RECFA, the restriced European Committee for Future Accelerators. She enjoys outreach activities and was elected among the leading women in science and technology by two Austrian magazines. Claudia is also a licensed radio amateur and plays the cello and the piano.

After research on W bosons with the ALEPH and DELPHI experiments at LEP, Jorgen joined CMS in 2003 through the Silicon Tracker project. Together with a team of technicians and engineers, he has worked on hundreds of qualified Tracker Endcap modules. At the same time he initiated studies on vertex and jet reconstruction, leading to novel analyses in top quark physics. During the years 2007 and 2008 he became the first top-quark convener within the CMS Collaboration, whereafter he became CMS team leader at the Vrije Universiteit Brussel. From 2011 he is the director of the VUB part of the Inter-university Institute for High Energies in Brussels, where he also initiated a new research team on LHC phenomenology. Today the institute embraces about 80 members. At the faculty he is chairing the Physics Department.

His current interests are in the search for new physics connected to top-quark processes and supersymmetry, as well as in the upgrade project for the CMS Tracker. In 2011 he was one of the two main organisers of the CMS week in Brussels. Jorgen is the Belgian representative in RECFA, the restricted European Committee for Future Accelerators, as well as in IPPOG, the International Particle Physics Outreach Group. In CMS he chaired numerous ARC's and was promotor of two Thesis Award winners.

Although physics is a passion for Jorgen, when he is creative in his well-equipped kitchen he enjoys a good glass of wine, with a preference for the Merlot grape. He lives in the countryside in Belgium where he has installed a painting atelier in his house. You can find him there when he is not lost among a vast series of books or playing with his two year old daughter in his garden.
