D. R. Upadhyay, Ph.D.
Tribhuvan University, Central Department of Physics, Institute of Science and Technology, Tribhuvan University, Nepal
About
I have been working as a lecturer (उपप्राध्यापक) of physics at Tribhuvan University, Nepal, since May 7. In March 2026, the 31st, I received my Ph.D. in Physics from the Institute of Science and Technology, Tribhuvan University, Kathmandu, Nepal related to radioactivity and ionizing radiation interaction and transport through construction materials and natural rocks. Furthermore, in 2014, I received my M.Sc. (Physics) from the Central Department of Physics, Institute of Science and Technology, Tribhuvan University, Kathmandu, Nepal. I have supervised more than two dozen B.Sc. project works, four M.Sc. project works, a dozen M.Sc. term papers, and 6 master's dissertation works. Moreover, I am also ISO 9712 Level 2 certified personnel in nondestructive methods for welding, casting, and corrosion mapping, such as radiography testing (film and digital), ultrasonic testing, liquid penetrant testing, and magnetic particle testing. Additionally, I qualified for the Digital Radiography Testing level 3 examination and received training about phased array ultrasonic testing.
