I obtained my PhD in 1997 on studying electroweak physics with the DEPHI
detector at the LEP e+e- collider. During these years, my activity was entirely
devoted to data analysis. But considering particle physics requires contribution
in different fields, I devoted the following 5 years to design and built a
silicon strip detector for the STAR experiment at the RHIC heavy ion collider.
And then I dipped back to data analysis with the STAR data to study
thermo-hydro-dynamics of quantum chromodynamics (often called quark gluon plasma
study).
Since 2006, I have joined the group in Strasbourg who pioneered the usage of
CMOS pixel sensor for tracking charged particles bringing unprecedented
performances in this domain. We are now involved in several upgrades of running
experiments: STAR at RHIC, ALICE at LHC, BES III at BEPC and in developments for
future accelerators: ILC, CLIC, SuperB, and FAIR. Also we explore how this
device may bring "new eyes" to other sciences by detecting single photons,
X-rays, electrons, protons or ions.

My lecture intends to provide an overview of all activities involved by tracking
and vertexing with a special emphasis on the description of detection systems
and not only detection techniques. We will explore the strategy of several
experiments, discover their detectors and the algorithm that allows to transform
series of electronics signals into intelligible objects like tracks and vertex.
Our conclusion will focus on the performances obtained by present systems and
expected by future ones.
