Research interests

Dr. Saha’s research activities include (a) mechanics of materials; (b) comprehensive micro/nano-mechanical modelling, analysis and design of periodic composite and smart composite materials such as hexagonal honeycomb sandwich shells, rib-reinforced smart composite plates, network-reinforced smart composites with orthotropic reinforcements, three-dimensional spatial composite networks and others; (c) design, manufacturing, testing and characterization, and applications of nanostructured materials and coatings; (d) cold spraying; (e) nano-surface and interface engineering focusing on strategic application areas including energy and environment, industrial manufacturing, large-scale infrastructure, among others.

Dr. Saha’s strength in research and innovation is tied with the fact that the work has always been directly linked with industry partners. In recent past he has led the applied R&D at two advanced nanomaterials and structures companies in Calgary. He has served as the Chair of Composites and Heterogeneous Materials Technical Committee of the American Society of Mechanical Engineers (ASME) Materials Division, as well the founding member of the Joint Canada-USA Regulatory Cooperation Council (RCC) on developing strategies for nanomaterials including risk assessment and management and uses of industrial nanomaterials.
