Postdoctoral research fellow at National Taiwan University, India
Dr. Niranjan Choudhry holds a PhD in Mechanical Engineering from IIT Guwahati, specializing in the design, additive manufacturing, and performance evaluation of auxetic structures, supported by MHRD scholarships for both PhD and M.Tech., along with a strong academic record including distinction throughout B.E. and being a school topper. His research focuses on high-performance lightweight cellular auxetic materials with negative Poisson’s ratio, covering geometric design, numerical modelling of elasto-plastic and fracture behaviour, theoretical framework development, and extensive experimental validation using advanced 3D printing techniques such as FDM, SLS, and photon printing. He has developed novel auxetic structures, cementitious and PU-foam composites for energy absorption, and cellular mechanical systems for cyclic damping applications while also working on shape memory alloys to establish composition–processing–property relationships through AI and machine learning. He has postdoctoral experience at National Taiwan University (NTU) working on high-entropy shape memory alloys, superelasticity, elastocaloric behaviour, and strain glass characteristics, and at NTUST where he contributed to auxetic metal design, stents, dental implant geometries, lattice-based damping systems, 3D concrete printing, and organized the India–Taiwan International Symposium on Additive Manufacturing 2024. He has supervised PhD and Master’s students, aided MoUs between IITs and NTUST, collaborated with industrial partners like Everplast, and served as a reviewer for the Additive Manufacturing journal. His earlier roles include JRF at IIT Guwahati on underwater tourism via 3D-printed coral reefs, Assistant Professor teaching core mechanical subjects, and a trainee engineer in casting quality inspection. His technical strengths include Python and Weka for AI/ML, SolidWorks, AutoCAD, Fusion360 and nTop for CAD, Abaqus for simulations, OriginPro, DOE and ImageJ for analysis, and hands-on expertise in additive manufacturing, optical and SEM characterization, and mechanical testing using UTM.
