My thesis is based on CERN (Switzerland) experimental data. My research interests were focused on hadron, lepton and heavy-ion induced reactions working in many National and International laboratories such as TJNAF (USA), CERN (Switzerland), TRIUMF (Canada) and SNOLab (Canada). Working at The Catholic University of America (USA) and Radboud University of Nijmegen (The Netherlands), as well as at Yerevan Physics Institute (Armenia) my research focus was on Bose-Einstein correlation and intranuclear collision effects. Along with research, I have taught courses when I was working at the University of Alberta and at The King's University. As an experimental physicist, I have designed and constructed technical detectors such as electromagnetic calorimeters, photomultipliers and particle detectors for the above-stated research projects.

Working already more than ten years at Athabasca University I enjoy helping students with home lab kits and in-person labs.

Research interests

Hadron, Lepton and Heavy-Ion induced reactions
Intranuclear Collision Effects
Bose-Einstein Correlation
Electroproduction and photoproduction of mesons
