Bilor is involved in the research and product development projects of Precision Sensors & Instrumentation, LLC (PSI Ltd. ‒ www.psi.am), the Armenian company which is developing and producing sensors based on a new principle of operation technology (SFCO‒sensors) invented by the company’s founder. He was also involved in research projects of the center on “Superconductivity & Sci. Instrumentation,” founded in 2007, in frames of the NFSAT-CRDF project (award # UCEP 07/07, 2007‒ 2010). He has investigated and explained the weakly expressed behavior of the normal to Super-Conductive (SC) phase transition. He also took active participation in designing the new test-instrument (“magnetic-field” probe) for “visualization” of super-fine superconductive properties of thin plate-like high-temperature SC materials (so-called FFLO effect) by the use of the new principle of operation above SFCO measurement technology.

Bilor is the team leader of Armenia in the International Physics Olympiads since 2012 (to date) and prepares the national team and students of the Special Physics-Mathematical (Phys-Math) School for physics Olympiads. He has been a jury member of the International Experimental Physics Olympiad in 2018 and 2019.
