My research interests are in theoretical high energy particle physics. The interpretation of experiments with particle beams at the colliders: the LHC at CERN, RHIC in BNL and HERA at DESY (in the past) requires the use of quantum chromodynamics (QCD) - the basic theory of the strong interactions. My studies aim at the understanding of mechanisms of the strong interactions. In particular, I work on

• experimental signatures of parton saturation
• nonlinear evolution equations in QCD
• multiparton scattering

My seminal paper on parton saturation, written together with Mark Wuesthoff, has become classics in the field of high density QCD, being cited more than 1000 times.
