Biography

Hitesh Kumar is an Assistant Professor in the Department of Mechanical Engineering at Thapar Institute of Engineering and Technology, Patiala. Prior to this, he was a Research Scholar at IIT Bombay. He did his Master's (M.Tech.) from Thapar University, Patiala.

His doctoral research focuses on microstructure, alloying, and oxidation kinetics. He is an active researcher in the field material characterization. During his Ph.D., he extensively used techniques like EBSD (Electron backscattered diffraction), TEM, XRD (X-ray diffraction), LRS (Laser Raman Spectroscopy), and XPS (X-ray photoelectron spectroscopy) for determining the microstructural phase(s), chemical nature, and composition of the oxide scale. He has also published 10 research papers during his Ph.D. in reputed journals like Acta Materialia and Scripta Materialia.
