Scientific interests:

Elementary particle physics, or high energy physics (HEP). Research Focus: Quantum chromodynamics (QCD), heavy flavor and top quark physics, neutrino physics.
I have published 120 scientific papers in reviewed journals (including European Physical Journal C, Nuclear Physics B, Physics Letters B, Journal of High Energy Physics, Physical Review D, Physical Review Letters) in high energy physics and about 30 papers in nuclear physics. Citations per paper (average): 33.4.
Very extensive experience in the analysis of experimental results in different large internayional collaborations, e.g. ZEUS(electron-proton collisions, ep), D0 (proton-anti-proton collisions,pp), HERA-B (proton-nuclei collisions, pA) etc.
1978-1994: was involved in nuclear spin physics studies at low energies on cyclotrons and development of next generation of experiments with sources of polarized protons and ions. PhD thesis was devoted to the measurement of the polarized recoil β-active nuclei from nuclear
reactions. I have about 30 publications in nuclear physics.
1994-2005: Member of the HERA-B Collaboration at HERA (DESY, Germany).
of the international HERA-B collaboration at the HERA accelerator. Goal of the experiment: study of the production and decay of heavy quarks in hadronic interactions. I have 19 joint papers in reviewed journals .
1997-2002: LHCb Collaboration at CERN . Participation in development of the LHCb online system, development Radiation monitoring system for the LHCb Inner Tracker. There are 3 my publications devoted to these topics.
2005 – present: Member of the ZEUS Collaboration at HERA (DESY, Germany). Physics coordinator of the Heavy Flavour group and joined physics analysis group. The Heavy Flavour group focuses on the production of charm and beauty quarks at HERA. The processes by which these heavy quarks are produced give fundamental insights into QCD and the structure of the proton and photon. We measure charm and beauty cross-sections over a wide range of Bjorken x and Q2 using heavy mesons (particles that contain heavy quarks) or leptons (such as electrons and muons) from the weak decay of the heavy quark. Group leader of the Kyiv group participating in the ZEUS experiment. I have published 81 papers in the ZEUS experiment.
Since 2010 up to present: Member of the DØ Collaboration at Tevatron, the Fermi National Accelerator Laboratory (Fermilab, USA). The DØ experiment consists of a worldwide collaboration of scientists conducting research on the fundamental nature of matter. The experiment is a test of the Standard Model of particle physics. The research is focused on precise studies of interactions of protons and antiprotons at the highest available energies. The 12 joint publications in reviewed journals were published.

Future Projects and Goals: We are actively involved in the development of next generation of experiments in elementary particle physics including neutrino experiments: WA105 at CERN and DUNE at Fermilab, USA as well as detector FCAL at DESY(Zeuthen), Germany for the future linear collider;  participation in the Belle II experiment at the KEK (Japan) is the focal point of the Kyiv HEP group’s long-term research vision.
Since 2016: Collaborations DUNE and WA105 (at Fermilab USA and CERN).
Since 2016: Collaboration FCAL (at DESY-Zeuthe, Germany): The group is also involved in preliminary research and development for a possible future detector for International linear collider (ILC). FCAL is a worldwide detector Research&Development collaboration.
Since 2013: Collaboration BELLE II (at KEK, Japan): The B-factory experiments observed the first large signals for CP violation (matter-antimatter asymmetries) in the B meson sector.
