Research

During my Ph.D., I have been working, under the supervision of Dr. J.R. Cudell, on the proton structure functions, especially on the small-x region. The main aim of my work was to have a escription of the experimental measurements coherent with the DGLAP equation at large Q² and Regge theory at small-x. I have also worked independently on the structure of the QCD vacuum, using light-cone quantisation, and on the semi-classical approach to compute the gluon distribution at small x.
As a Postdoc, I am studying saturation and fluctuation effects in perturbative high-energy QCD in collaboration with the SPhT at the CEA Saclay and the Nuclear Theory group at the Brookhaven National Laboratory. This field of research covers the structure QCD in its high-energy limit, its universal links with statistical physics and the applications to phenomenology.
Since a few years, three years I mostly work on jet physics with G. Salam and M. Cacciari. We have developped new algorithms (SISCone, anti-k_t) and new analysis techniques (e.g. jet areas), both analytically and in their applications to jet physics at the LHC.
