Dr. Rashi Tyagi is currently working as an assistant professor in University Centre for Research and Development at Chandigarh University. Dr. Tyagi has won CII MILCA AWARD in the field of tribology of electrical discharge coating in 2022. She has completed her PhD in mechanical engineering from the Indian Institute of Technology (Indian school of mines), Dhanbad, India. Her PhD work was focused on surface modification by an electrical discharge process for solid lubrication and enhanced tribological performance. She has completed her MTech from IIT(ISM), Dhanbad, India. She has done her MTech project on the fiber laser cladding of TiN+SS 304 powder to enhance tribological performance. She has published over 21 SCI articles in peer-reviewed international journals, conference proceedings, and book chapters as a first author in the field of 3D printing and tribology of coatings. She has published two articles in Tribology International. She is also a reviewer in several SCI and Scopus indexed journals. She is currently working on tribology of fiber reinforce composite prepared by fused filament fabrication, fused deposition modeling, thermoplastic polymers, and natural and synthetic composites.
