About the Author

Dr. Raj C. N. Thiagarajan is an engineering researcher, innovator, and author with more than three decades of experience in advanced engineering, computational modelling, product innovation, and technology development. He is the Managing Director of ATOA Scientific Technologies Pvt Ltd, where he leads Atom TO Application technologies.

Dr. Raj holds a Bachelor's degree in Engineering, a Master's degree in Technology, and a Ph.D. in Smart Structures.  He is an alumnus of ACCET, IITB, and Cranfield University UK. His pioneering doctoral research on self-sensing carbon fibre reinforced composites using electrical resistivity measurements made significant contributions to structural health monitoring and intelligent composite structures. The research was recognized with the Safety Award in Mechanical Engineering by the Institution of Mechanical Engineers (IMechE), United Kingdom, acknowledging its innovation and potential impact on engineering safety.

During his distinguished career, Dr. Raj has worked with leading organizations including IITB, , DRDO, TATA, and GE Global Research, contributing to the development of innovative engineering products and advanced technologies. His expertise spans computational Multiphysics analysis, smart materials, advanced composites, nanotechnology, renewable energy systems, digital engineering, product innovation, and technology commercialization.

He is the architect of the M5 Digital Engineering Framework, integrating Multimaterial, Multifunctional, Multiscale, Multiphysics, and Multimodal engineering into a unified methodology for accelerating innovation from concept to commercialization.

Dr. Thiagarajan's research interests include smart materials and smart structures, self-sensing composites, structural health monitoring, artificial intelligence for engineering systems, digital engineering, computational Multiphysics, advanced materials, nanotechnology, energy harvesting, autonomous systems, and engineering innovation.

He has authored numerous technical publications and holds several patents. A frequent keynote speaker, industrial trainer, and visiting faculty member, he has inspired engineers, researchers, entrepreneurs, and students to adopt multidisciplinary thinking and innovation driven engineering.

His books include Digital Engineering Innovation: a practitioner-focused CAE Technology and Tools for Breakthrough Engineering Innovation; Technology and Innovation Management: A Practical Guide, which bridges engineering innovation with technology commercialization and business strategy; Ultrasound and CMUT Technologies, a comprehensive reference on next-generation ultrasound systems, capacitive micromachined ultrasonic transducers, wearable ultrasound technologies, and intelligent medical imaging; and Play Innovation, recipient of the Golden Book Award (2025) and a key contributor to his recognition among the "50 Most Influential Authors of 2024" by Delhi Wire.

In  his latest book, Smart Structures and Smart Materials, Dr. Thiagarajan distils decades of research, industrial experience, computational engineering, and systems thinking into a comprehensive and technically rigorous guide to one of the fastest-evolving fields in engineering. By integrating the fundamentals of smart materials with artificial intelligence, self-sensing composites, digital engineering, structural health monitoring, digital twins, edge intelligence, and autonomous systems, the book presents a unified vision for the future of intelligent engineering.

"The future belongs to engineers who can seamlessly integrate materials, physics, computation, artificial intelligence, and human creativity into technologies that make the world smarter, safer, healthier, and more sustainable."

"Great engineers don't just predict tomorrow—they design it."

"Dream, Design, and Innovate—the future belongs to engineers who create."
