Roos, Lydia

Lydia Roos is research director at the CNRS. During her PhD studies in Marseille she studied properties of beauty mesons from data obtained with the ALEPH experiment at the LEP collider. In 1993 she joined a CNRS laboratory in Grenoble and worked on the construction and operation of a silicon pixel detector for the experiment DELPHI on the LEP. In 1996 she started working in the Laboratory for High Energy Physics in Paris. Her activities were on the matter–antimatter symmetry studies with the BaBar experiment in Stanford, USA. During a four-year stay in Beijing devoted to fostering the Franco-Chinese scientific collaboration, she led an associated international laboratory for elementary particle physics studies. At her return to Paris in 2008, she joined the ATLAS experiment. Since then she worked on the Higgs search, investigating the relevant backgrounds, and the study of Higgs boson properties.
