My current research activities focus mainly on jet physics. With G.P. Salam and M. Cacciari, we have introduced three tools widely used at the LHC: the antik t algorithm, FastJet (a package for jet finding), and a strategy for pileup subtraction. A fraction of my research today is focused on an analytic understanding of jet substructure and related topics.
More generally, I am interested by LHC phenomenology and QCD in particular. For example, I also study the highenergy limit of QCD with the group at the IPhT in CEA Saclay, an activity that I started when I was a PostDoc at the IPhT and pursued at the Brookhaven National Laboratory.
My earlier research experience, during my PhD, focused on the proton structure functions and the interplay between perturbative QCD and Regge theory. I have also worked independently on the structure of the QCD vacuum, using lightcone quantisation.
