Tae-Jeong Kim has joined Florencia Canelli as Deputy Spokesperson, working with Anadi Canepa as Spokesperon for the CMS Collaboration for 2026-2028.
Now with over 6000 people, CMS remains one of the world’s largest scientific collaborations. The collaboration welcomes Tae-Jeong Kim in his new position, and thanks outgoing Deputy Spokesperon, Hafeez Hoorani, for representing CMS from 2024-2026.
Tae-Jeong Kim (CMS Deputy Spokesperson 2026-2028) is a full Professor at Hanyang University. He received his PhD in Physics (Experimental Particle Physics) from Korea University in 2007. He searched for a doubly charged Higgs boson at the D0 experiment at the Tevatron. As a postdoctoral researcher at the University of Iowa, he implemented the Particle Flow Algorithm (PFA) and muon identification for the International Linear Collider.
He joined the CMS in 2009 and contributed to the first CMS paper about the transverse-momentum and pseudo-rapidity distributions of charged particles. He also contributed to the commissioning of the Particle Flow Algorithm at the start of CMS. He worked on various top quark physics topics and chaired the top quark physics subgroups. He also served as a Physics Analysis Tool (PAT) coordinator for offline computing software (2013-2014). He became an assistant professor at Jeonbuk National University in 2014 after postdoctoral work at VUB (Brussels University). Then he moved to Hanyang University as an associate professor in 2015 and rejoined CMS as a team leader. He contributed to the muon system as the RPC IB chair (2019- 2022) and deputy muon system manager (2023-2025).
Anadi Canepa (CMS Spokesperson 2026–2028) is a senior scientist at Fermi National Accelerator Laboratory. She began her research with the CDF experiment at the Tevatron, focusing on searches for new phenomena and the Higgs boson, and contributing to upgrades of the silicon tracker and trigger system (PhD, Purdue University, 2006). In 2008, she joined the ATLAS Collaboration as a board-appointed scientist at TRIUMF. During the experiment’s startup, she contributed to data taking and data preparation and went on to serve in several leadership roles, including convener of the SUSY EWK Physics Group and the Upgrade Physics Group.
In 2015, she became a scientist at Fermilab and joined the CMS Collaboration. At the laboratory, she led the CMS group—now the Collider Division within the Particle Physics Directorate—for six years. She also served as strategic planning leader for the Energy Frontier, scientific secretary of the Physics Advisory Committee, and Director of User Facilities and Experiments. Within the CMS Tracker organization, she was appointed OT Beam Tests and System Tests Coordinator and served as manager for Outer Tracker Electronics in the U.S. project. She was appointed CMS Deputy Spokesperson during Gautier Hamel de Monchenault’s term of office (2024–2025).
Her broader service includes membership on numerous national and international panels, chairing the Division of Particles and Fields of the Canadian Association of Physicists, and serving as the North American representative to the 2026 update of the European Strategy for Particle Physics.
Florencia Canelli (CMS Deputy Spokesperson 2026–2028) is full Professor of Physics at the University of Zurich. Her research focuses on the top quark and the Higgs boson, as well as searches for new phenomena, including dark matter, at particle colliders.
She began her research at the D0 experiment at the Tevatron (PhD, University of Rochester, 2003), where she measured top-quark properties. Her thesis was recognized with the Mitsuyoshi Tanaka Dissertation Award of the American Physical Society. After postdoctoral work at UCLA on the CDF experiment, she was awarded the Wilson Fellowship at Fermilab and later joined the laboratory's scientific staff, co-leading the CDF Top Quark group at the time of the first observation of single top quark production. In 2008, she joined the University of Chicago as Assistant Professor and member of the ATLAS Collaboration at CERN, becoming Associate Professor in 2011. During this period, she received the Alfred P. Sloan Fellowship and the IUPAP Young Scientist Prize.
Since joining the University of Zurich and the CMS Collaboration in 2012, she has held leadership roles within CMS, including Convener of the Top Quark group (2018–2020), Physics Coordinator (2021–2023), and Switzerland's representative on the CMS Management Board (2013–2021). Her group played a leading role in the Phase-I CMS pixel detector upgrade and is now a major contributor to the Tracker Endcap Pixel detector for the Phase-II upgrade at the HL-LHC.
She serves on national and international advisory panels and committees. She was a member of the Physics Advisory Committee to the Director of Fermilab (2017–2020), served as a member and Chair of the C11 Commission on Particles and Fields of the International Union of Pure and Applied Physics (2015–2024), and is Switzerland's scientific delegate to the CERN Council since 2021.
