The ATLAS collaboration welcomes its new management team, who began their mandate in March 2025. Succeeding Andreas Hoecker as ATLAS Spokesperson is Stéphane Willocq (University of Massachusetts Amherst). A long-standing ATLAS member since 2004, he brings extensive leadership experience to the role, having previously served as Deputy Spokesperson, ATLAS Physics Coordinator and Chair of the Publications Committee. Joining him in the new management team are Deputy Spokespersons Anna Sfyrla (University of Geneva) and Guillaume Unal (CERN), alongside returning members Technical Coordinator Martin Aleksa (CERN), Resources Coordinator David Francis (CERN) and Upgrade Coordinator Benedetto Gorini (CERN).

The new team, who have been elected for a two-year term, will steer ATLAS through the final phase of LHC Run 3 and navigate the transition into the High-Luminosity LHC (HL-LHC) era. This is a pivotal moment for ATLAS as the collaboration prepares for extensive upgrades to the experiment.

“I want to express my deep gratitude to Andreas for his leadership and dedication to ATLAS,” says Willocq. “During his two terms as Spokesperson and two preceding terms as Deputy Spokesperson, he played a key role in advancing our scientific programme and strengthening our collaboration. We are building on a solid foundation thanks to his efforts. I also want to extend my appreciation to Manuella Vincter for her six years as Deputy Spokesperson. Her commitment to ATLAS and its members has been invaluable.”

“The strength of ATLAS lies in its people,” Willocq continues. “Our collaboration spans the globe, bringing together individuals from diverse backgrounds and areas of expertise to tackle some of the most profound questions in nature. As we set course for the HL-LHC era, we can do so with confidence, knowing that our collective efforts have consistently driven major scientific advances.”
