Varnadow Professor of Materials Science and Engineering
Oklahoma State University
Dr. Ranji Vaidyanathan is the Varnadow Chair Professor of Materials Science & Engineering in OSU’s School of Materials, Mechatronics and Manufacturing Engineering. He brings several years of entrepreneurship and product development in polymer composites and additive manufacturing. His record includes two book chapters, 72 peer-reviewed papers, a National Academies committee report, 100+ conference publications, and 80 conference/poster presentations. He is Associate Editor for both the International Journal of Applied Ceramic Technology and the SAMPE Journal. Honors include Fellow, National Academy of Inventors (2020) and Fellow, SAMPE (2021). He received an R&D 100 Award for water-soluble tooling materials now used worldwide for complex composite parts. He also advises OSU’s SAMPE student chapter.
Dr. Vaidyanathan’s technical background spans processing of polymer and ceramic composites (liquid molding, prepreg/autoclave, RTM, high-temperature ceramics) and additive manufacturing of metals, ceramics, polymers, and composite systems (SLM/EBM, binder jetting, DED, FFF). His recent work focuses on qualification and location-resolved characterization of metal AM parts, linking build thermal history to microstructure and local mechanical/fatigue properties to support data-driven design and certification.
