Experimental measurements of various aspects related to hadrons containing charm and bottom quarks. Main topics in which I'm interested are CP violation, rare decays and spectroscopy of heavy quark hadrons. I was pursuing this research on the CDF experiments at Tevatron accelerator at Fermi National Accelerator Laboratory from 2004 until 2010, when I moved on to LHCb experiment running at CERN's LHC accelerator. Main contributions during years at CDF are measurements of Bs mixing frequency and CP violation in Bs → J/ψφ decays, study of orbitally excited B0 and Bs0 mesons and properties of X(3872) particle. While work on LHCb is my main research, I'm also involved in maintance of the EvtGen code package, which is used in simulations for decays of b- and c-hadrons, and starting from January 2011 I'm member of particle data group which regularly published Review of Particle Physics.
