  • Worked on the data analysis of the JLab PRad Experiment (High Precision Measurement of the Proton Charge Radius). - • Carried out the analysis of the electric form factors of the proton at very low Q2 region for the first time and extracted the charge radius of the proton with sub-percentage accuracy which is important to clarify the “proton radius puzzle”. - • Developed a Geant4 simulation package with an independent fast optical model of the calorimeter for accurate detector… Show more • Worked on the data analysis of the JLab PRad Experiment (High Precision Measurement of the Proton Charge Radius). - • Carried out the analysis of the electric form factors of the proton at very low Q2 region for the first time and extracted the charge radius of the proton with sub-percentage accuracy which is important to clarify the “proton radius puzzle”. - • Developed a Geant4 simulation package with an independent fast optical model of the calorimeter for accurate detector response. - • Developed a set of event generators for elastic electron-proton scattering and Moller scattering to get more accurate radiative corrections. • Worked on the prototype manufacture of a Gas Cherenkov detector for the Solenoidal Large Intensity Device which will be used for JLab 12GeV upgrade. Also studied the behavior of the Hamamatsu multi-anode photo multiplier tube used in this detector in the magnetic field. • Co-spokesperson of JLab Proposal PR12-17-009 (Precision Deuteron Charge Radius Measurement with Elastic e-d Scattering). - • Developed a simulation package for this proposal to fine-tune the apparatus setup, study the background rejection and estimate the uncertainty budgets.
