Research Group: Laboratory for Extreme Mechanics & Additive Manufacturing

Short bio: Dr. Yu Zou joined the MSE Department at U of T as an Assistant Professor in January 2018, after working as a Postdoctoral Fellow in the Department of Mechanical Engineering at MIT. He received his doctorate, master’s, and bachelor’s degrees from ETH Zurich, McGill University, and Beihang University, respectively, all in Materials Science and Engineering. He was also a JSPS visiting scholar at Kyoto University. At U of T, Dr. Zou leads the Laboratory for Extreme Mechanics & Additive Manufacturing (LEMAM) and the research topics of his group include the design of novel metallic materials, multiscale mechanical testing, metal additive manufacturing (3D printing) and applied machine learning. At U of T, Dr. Zou is teaching “Mechanical behaviour of materials”, “Fracture and failure of materials” and “Additive manufacturing of advanced engineering materials”. Dr. Zou is currently serving as the Chair of Materials Technical Section in the Metallurgy and Materials Society of CIM (MetSoc) in Canada.


Research Interests

Our group uses novel experimental, analytical, and computational tools to explore materials with extreme properties or under extreme conditions, particularly for metallic materials. Our research themes can be summarized as 4Ms – metals, mechanics, manufacturing, and machine learning, covering many length and time scales. Of particular interest is to advance the fields of vital importance to the society, including aerospace, biomedical, electronic, environment, and energy sectors.

Metals: high-entropy alloys, nanocrystalline alloys, quasicrystals, titanium, aluminium and steels.

Mechanics: nanoindentation, in-situ instrumentation, high strain-rate/temperature deformation, fracture and failure analysis.

Manufacturing: additive manufacturing (3D printing), cold spray technology, mechanical alloying, arc melting, and magnetron co-sputtering.

Machine Learning: machine learning for alloy design, computer vision for advanced manufacturing
