March 2011

From 1984 to 2008, I worked on various topics of experimental particle physics at CERN. My Ph.D. thesis dealt with the measurement of the strong interaction coupling constant in the UA2 experiment, using W and Z events produced in hadronic collisions. Then, I moved to the e+e- LEP experiment DELPHI and worked both on the detector and on data analysis, searching for neutral Higgs bosons of different kinds (standard model, minimal supersymmetric model, 2 Higgs doublet model). I was convener of several search teams in DELPHI and member of the joint LEP working group on Higgs boson searches.

In 2006, I moved to observational cosmology and joined the SuperNova Legacy Survey, a second-generation ground-based Canadian-French experiment using distant Type Ia supernovae (SNIa) to study the accelerated expansion of the Universe. While pursuing data analysis in SNLS on SNIa photometric typing and redshift determination, I have recently become involved in the preparation of BigBOSS, a fourth-generation baryon acoustic oscillation project, whose aim is to precisely map the matter distribution of the Universe, offering a complementary way to study its accelerated expansion.

Beside research, I have been teaching particle physics since 1992, in second years of Masters and, more recently, to first and second-year Ph.D. students. The topic of my lectures will be an overview of the electroweak theory, from historical developments to the most precise tests established at LEP, SLC and the Tevatron.
