Biography:

I am interested in searching the physics beyond standard model (BSM) which would answer numerous unsolved problems, such as nature of dark matter, the origin of matter-antimatter asymmetry (baryogenesis), and finite neutrino masses. Most solutions
to these problems require new particles — such as axions, monopoles, dark photon or supersymetric particles. My current research involves searching for the axion-like particles using heavy ion (PbPb) collisions collected by the CMS experiment at CERN. These searches require the accurate estimation of the heavy ion (PbPb) data luminosity collected during the run. I am also involved in the luminosity measurement of PbPb collisions at sqrt(s_NN) = 5.02 TeV collected during 2018.
