Prof. Chiara Mariotti is an experimental high energy physicist and senior scientist at INFN (Istituto Nazionale di Fisica Nucleare), Turin, Italy. She earned her PhD working on the NMC experiment at CERN. Later, she joined the DELPHI experiment at the LEP accelerator at CERN, where she made significant contributions to the high-precision measurement of Standard Model parameters and initiated her work on the search for the Higgs boson.

Within DELPHI, she held multiple leadership roles, including coordination of analysis groups and overall physics coordination. Since 2000, she has been actively involved in the CMS experiment at the LHC, leading several teams focused on the Higgs boson search and, subsequently, on the precision measurement of its properties. In 2009, she founded and led the LHC Higgs Cross Section Working Group, which played a key role in the discovery and characterisation of the Higgs boson.

In recognition of her outstanding contributions, the European Physical Society (EPS) awarded her the Emmy Noether Distinction for Women in Physics in 2018. She is a Fellow of the European Academy of Sciences and an Adjunct Professor at Boston University.

Prof. Mariotti has served as Officer of the Physics Division since February 2022:

• First mandate: February 2022 – February 2025
• Second mandate: February 2025 – February 2028, following her re-election in 2025
