Prof. Rajarshi Banerjee
University of North Texas, USA
Dr. Rajarshi (Raj) Banerjee is a University Presidential Professor and Regents Professor in the department of materials science and engineering at the University of North Texas (UNT). His primary research focus is on advanced metallic and functionally-graded composite (or hybrid) materials for aerospace, energy, and biomedical applications. Materials of focus include titanium base alloys, high entropy alloys (HEAs), nickel (and cobalt) base superalloys, and magnetic alloys, processed via additive manufacturing (AM) technologies such as directed energy deposition (DED) and laser powder bed fusion (LPBF), as well as conventional thermo-mechanical processing. The use of advanced characterization techniques, spanning over a range of length scales, including scanning and transmission electron microscopy, electron backscatter diffraction (EBSD), focused ion beam based serial sectioning and tomography, and atom probe tomography (APT), constitute a common thread tying his multiple research activities. These techniques are used to identify the underlying mechanisms and phase transformations governing microstructural evolution and microstructure-property relationships in these complex multi-phase, multi-component materials systems. His research is funded at present by the National Science Foundation, Air Force Research Laboratory, the Army Research Laboratory, the national network for manufacturing innovation (NNMI) under the Lightweight Innovations for Tomorrow (LIFT) consortium, and multiple industries. He has over 300 publications in peer-reviewed journals, with over 17000 citations, and an H-index of 74 (Google Scholar). Dr. Banerjee also holds appointments as an adjunct professor in materials science and engineering at the Ohio State University in Columbus, Ohio, and as a visiting professor at Nanyang Technological University, Singapore and the Indian Institute of Technology, Bombay.
