Researcher
Dr. Srinivasan Nagarajan serves as a Research Scientist II at the Arbegast Materials Processing and Joining Laboratory (AMP Lab) at the South Dakota School of Mines and Technology, leading critical projects in additive manufacturing while advising undergraduate and graduate researchers. His expertise bridges advanced materials processing techniques with mechanical behavior analysis across multiple scales. His academic foundation includes: Ph.D. in Materials Science and Engineering from Homi Bhabha National Institute / Indira Gandhi Centre for Atomic Research Campus (2015) M.Sc. in Materials Science from Anna University/College of Engineering Guindy Campus (2009) B.Sc. in Physics from University of Madras/D.G. Vaishnav College (2007), graduating first rank with multiple awards Nagarajan's research centers on processing-structure-performance relationships in additively manufactured materials, with pioneering work in solid-state and hybrid methods. He specializes in cold spray deposition, friction stir processing, and wire direct energy deposition for structural steels, employing nondestructive characterization techniques like digital image correlation and full-field imaging. His investigations span microstructural evolution during deformation across length and time scales, revealing fundamental mechanisms in alloys including aluminum-magnesium systems and dual-phase steels. Analysis of his publication trajectory shows consistent innovation in hybrid additive manufacturing processes, particularly for stainless steels, with increasing emphasis on in-situ characterization techniques. His work demonstrates a clear progression from fundamental deformation studies toward applied manufacturing solutions, integrating thermomechanical analysis with advanced imaging to solve industrial challenges in automotive and aerospace sectors. His accolades include: INSPIRE Faculty Award (Department of Science & Technology, 2017) National Postdoctoral Fellowship (Science & Engineering Research Board, 2017) McMaster/General Motors Postdoctoral Fellowship (2015) Multiple Department of Atomic Energy research fellowships Throughout his career, Nagarajan has secured government and industry funding as principal investigator, established specialized laboratories across institutions in India, Canada, and the United States, and mentored numerous students. His collaborative approach spans national laboratories and academic centers, with current focus on optimizing cold spray-friction stir hybrid manufacturing at SD Mines' AMP Lab. He maintains active peer review roles for leading journals including Additive Manufacturing and Journal of Materials Science, driving methodological rigor in the field.
