Dr. Shyamsunder Mandayam is an innovator, researcher, technologist and  trainer with deep domain expertise in the multidisciplinary area of Nondestructive Evaluation (NDE) of materials, components and structures. He is currently the Chief Scientific Advisor for Azeriri Pvt Ltd and a Mentor for Teralumen Solutions Pvt Ltd. During his 36 years long career at Indira Gandhi Centre for Atomic Research, Kalpakkam, India and GE Research, Bangalore, India, he has worked extensively in the development of new and advanced NDE/Inspection techniques, driving the vision and preparing the roadmaps for next generation technologies in NDE for metallic and non¬metallic materials (composites) related to aerospace, nuclear, power, renewables and oil & gas industries. He has worked on several cutting edge domains and technologies like eddy current array sensors, POD, nonlinear ultrasound, positron annihilation, microwave and terahertz NDE, pipeline inspection, automation, robotics and lifing of components and structures. Currently, he is pioneering the adoption of NDE 4.0 in the industry through digital transformation (Robotics, Drones, Io T, Digital Twins, Analytics using AI and ML, AR and VR). He has 12 patents and 160+ papers in various journals, books and proceedings and delivered 90+ invited talks. Dr. Mandayam has received several prestigious awards like National NDT award for R&D, GE India’s JRD Tata award for excellence, GE Whitney award among others. He is a Honorary Fellow of ISNT and a Life Member of ASNT, MSI, AMSI, In SIS.
