I have been working as an Assistant Professor at the National Rail and Transportation Institute, Vadodara, since September 2020. Before joining NRTI, I worked at the Indian Institute of Technology Kanpur as Postdoctoral Fellow. I received Ph.D. and M.Tech in Tribological Design from the Indian Institute of Technology (ISM) Dhanbad. My research interests include wear of materials, lubrication, tribology of additive manufactured parts, and nanocomposites for industrial application. Postdoctoral students interested in joining NRTI with external funding from Government agencies like SERB NPDF, CSIR-Pool Scientist scheme, UGC fellowship, etc., are encouraged to apply. The application material (cover letter, project proposal, and brief CV) can be directed to the e-mail: ram.upadhyay@nrti.edu.in
