Research interests: microjoining; wire bonding; laser and resistance microwelding; diffusion brazing; nanojoining and nanofabrication
Professor Norman Zhou’s program fosters quality research in micro- and nano-joining, and aims to strengthen Waterloo’s position as a global leader in this area.
Zhou is the Director of the Centre for Advanced Materials Joining (CAMJ) at Waterloo. Under Zhou’s direction, and in accordance with the chair project, the primary goal of CAMJ is to develop new and innovative technologies for materials joining, including micro- and nano-joining. CAMJ collaborates with leading companies in the industry for research and development. In addition, CAMJ trains students at all levels and collaborates with students from foreign institutes of excellence to extend the research to a global scale.
Zhou earned his PhD from the Department of Metallurgy and Materials Science, University of Toronto, Toronto, Canada. Zhou worked as a Materials Scientist at the Fuel Development Branch, Atomic Energy of Canada, Ltd, Chalk River, Ontario, Canada and also worked as a Senior Research Engineer at the Microjoining and Plastics Group at the Edison Welding Institute, Columbus, Ohio, U.S.A. Zhou has published over 100 peer reviewed journal papers and recently edited the first comprehensive book on microjoining and nanojoining.

Increasing scientific understanding of micro- and nano-joining
In his role as Canada Research Chair in Microjoining, Dr Zhou is focused on developing new or improved micro- and nano-joining processes and on increasing scientific understanding of micro- and nano-joining. Research on topics such as bonding mechanisms and metallurgy, thermal stresses and distortion, and numerical modeling are underway. Several projects intend to address technology areas of immediate interest to the telecommunications and medical industries, including hermetic sealing and microjoining of advanced materials – particularly dissimilar material combinations.
Microjoining techniques for device manufacturing
Joining is a fundamental requirement in manufacturing of industrial products, and includes welding, brazing, soldering, adhesive bonding and other technologies. Microjoining has its roots in electronic packaging and interconnection, but is essential for manufacturing devices such as medical implants, sensors and transducers, batteries, optoelectronics and micromachines. Dr Zhou’s research goal is to develop practical interconnection and construction technologies of nano-mechatronics and molecular devices. This research will lead to the fabrication of nanodevices with distinguishable properties, superior sensitivity, high integration and low energy cost.
Nanojoining techniques for energy, environment and optoelectronics applications
In the area of nanotechnology, Dr Zhou studies nanojoining and nanofabrication, such as joining of Carbon Nanotubes (CNTs) and other nanoscale building blocks, and fabrication of nanomaterials, such as Boron Nitride (BN) nanotubes and ZnO nanowires to assemble 3D nano-tailored architectures for energy, environment and optoelectronics applications. Dr Zhou is also interested in studying the growth of TiO2 nanowire membranes for water treatment, aligned TiO2/ZnO nanowire arrays for solar cells, and minimeter-long ZnO nanowires for nanowave guide, micromechanical sensors and nanogenerators.
