During the Ph.D. program, Avijit Ghosh studied the defects mediated optical properties of ZnO based nanostructures. After that he worked as a Lecturer at the department of Physics, Rajiv Gandhi University of Knowledge Technologies, Basar, Telangana, India. Since June 2011, he has been working as an Assistant Professor at the Department of Physics, Central University of Jharkhand. Ranchi, India. He has guided/guiding 31 master students for fulfillment of their dissertation and 2 Ph.D. students are now working under his supervision. He has published/communicated more than 24 research articles and presented his research contribution in national/international conferences regularly. He is a reviewer of several international journals like Applied Physics A: Materials Science & Processing, Applied Physics Letters, Journal of Non-Crystalline Solids, Journal of Applied Physics, Nanotechnology, Philosophical Magazine, Physica Scripta, Journal of Raman Spectroscopy,etc. and a Life Member of Indian Association of Physics Teachers. He worked on the project of “Effective power generation through ZnO-based piezoelectric Nanowires” at departamento de Física e Astronomia, da Universidade do Porto, Portugal through Erasmus Mundus LEADERS´scholarship program on Post-Doctorate level funded by European Union during 2017-2018. He was awarded Focus Area Science Technology Summer Fellowship funded by IASc (Indian Academy of Sciences)-INSA (Indian National Science Academy)-NASI (The National Academy Sciences, India) (University of Hyderabad, India) in 2023. Recently, Dr. Ghosh acts as a Managing Guest Editor for Materials Today: Proceedings on CMDAYS-2021.
