Research Interests

  • Research and development of particle detectors
  • Simulation of physics processes and detector response
  • Test of Electroweak sector of the Standard Model
  • Search for Higgs and Supersymmetric particles
  • Precision measurements of particle properties


Elementary particles and their interactions are described by the Standard Model (SM).
The SM has been very successful in its predictions, as well as in accounting for a variety
of experimental outcomes. Despite its extraordinary success, there are strong conceptual
 indications that the SM is incomplete. Moreover, one of the most important ingredients
of the SM, the Higgs boson -- the particle responsible for the origin of mass -- has not
been discovered yet.

My current research is focused on tests of the SM, measurements of  its parameters and
on the searches for the Higgs particle. One of the parameters of the SM is mass of the top
quark, which is the heaviest elementary particle observed so far. I have been working  on the measurement of the top quark mass using data recorded by D0 experiment at Fermilab's
Tevatron collider. The Tevatron is world's  highest energy accelerator and the only facility
capable of producing the top quarks.

Later in the decade, CERN's Large Hadron Collider will take over from the Tevatron as a
next generation accelerator. Two general purpose detectors, CMS and ATLAS, will record
events produced in proton-proton collision at LHC. With its gigantic energy and high
luminosity, LHC  promises to be a true discovery machine. As a member of the CMS
Collaboration I have been investigating LHC potential for the  discovery of Higgs boson
and other particles predicted by theories beyond the SM.
