Research

I'm a scientist working at the High Energy Physics Division of the Argonne National Laboratory (USA). My current experiment is ATLAS/LHC (http://atlas.ch/) at CERN. In the past I was a member of the ZEUS experiment (https://www-zeus.desy.de/) experiment at DESY (1998-2009) and the L3 experiment (http://l3.web.cern.ch/l3/) at LEP (1995-1998). I've contributed to experiments with >1400 publications, and wrote 15 papers for large-scale international experiments. I'm a primary author of more than 200 published articles and two books on data analysis (by Springer).

Among major physics highlights, I was a primary author of highest-precision F2cc measurements used to understand charm structure of the proton, evidence for strange pentaquarks (not confirmed) in ep collisions, a first observation of the strange sea at HERA, a first observation of direct (anti) deuterons in ep. In 2011, I led a group of scientists measuring photons (quanta of light) at the highest energy (more than 1 teraelectronvolt or 10^12 electron volts) ever produced by humans in a laboratory environment. In 2021–2023, I led a group of LHC scientists to publish the first paper in elementary particle physics in which all collision events from the LHC collider were converted into event "replicas" using a deep unsupervised neural network for searches for new physics.

Preferred physics areas of my interest include (but are not limited to) the following: QCD analysis, jets in DIS and pp, heavy flavor (charm in DIS), strange particle production, pentaquarks, prompt photons in photoproduction and hadron collisions, Higgs studies, particle correlations and fluctuations, multiplicity moments, multiplicity properties of the current/target regions in the Breit frame of DIS, charm production in DIS, intermittency phenomenon (both theoretical and experimental study), Bose-Einstein correlations/interference (one- two- three- dimensional study in Longitudinal Center-of-Mass System, with different backgrounds, Bose-Einstein correlations of hadrons from different W at LEP2 energies), multiparticle production models (QCD based, phenomenological analytical and Monte-Carlo models), studies of top quarks at the NLC.

I was a member of the following experiments:
