Current Research

My research interests span the field of experimental particle physics, heavy ion physics, and energy frontier physics. I am a member of Electron Ion Collider (EIC) collaboration at BNL and soon going to join ALICE Collaboration at LHC (proposal approved). In past, I worked on studying the production of top quark pairs (tt-bar) in proton-lead collisions and measurements of photon-induced processes in Ultra-Peripheral Collisions (UPC) of heavy ions with the ATLAS detector. We discovered light-by-light scattering (yy -> yy) in heavy-ion collisions in 2019.
Before joining ATLAS collaboration, I worked on studying the Multiple Parton Interaction (MPI) and multiplicity dependence of charged particle and strange hadron production in pp collisions with the ALICE collaboration at LHC. My dissertation involved around the search for a heavy baryon resonance state, ^_b^*0, in Collider Detector at Fermilab (CDF) data as predicted by Standard Model (SM). We have found the first evidence of the bottom baryon resonance state in 2013 at Fermilab.

Present research interests:
-Jet quenching in small systems and heavy ion collisions at LHC energies
-Photon-induced processes in Ultra-Peripheral Collisions (UPC)
-Detector and Software development for the future EPIC detector at Electron Ion Collider (EIC)
-Dijets and inclusive jets in photoproduction processes at EIC
-Phenomenology of Quark Gluon Plasma and Deep Inelastic Scattering
