Past that he joined the Department of PMSE, JIIT, Noida for his PhD degree. In 2010 he got Senior Research Fellowship from CSIR, New Delhi and worked full time as a SRF in CSIR-National Physical Laboratory, New Delhi where he has completed his PhD research work and got PhD degree on 17th June, 2013. He feels very fortunate to have Dr. H.K. Singh, Principal Scientist in CSIR-NPL and Dr. R. K. Dwivedi, Associate Professor in JIIT, Noida as supervisors for his PhD thesis. After his PhD, he got a Research Associate position at IUAC, New Delhi in June, 2013 where he got an opportunity to work with Dr. K. Asokan, Scientist-F, IUAC, New Delhi for his post-doctoral work on Swift Heavy Ion Irradiation Effect on Manganites thin films. He has published several research papers in International journals indexed in global research database Web of Science (SCIE) and SCOPUS. He also presented many research papers in international conferences. He also attended several workshops and conferences.

On 15th July, 2014 he joined K. R. Mangalam University as an Assistant Professor of Physics in School of Basic & Applied Sciences. He is currently teaching physics courses to M.Sc. Physics, B.Sc. (H) Physics, and B.Tech students. Apart from teaching he is also involved in research work and supervising students for PhD degree he is also involved in many activities of the University.
