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 high-entropy alloys and nanocrystalline alloys, nanomechanical testing, and metal additive manufacturing (3D printing).

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 includes metals, mechanics, manufacturing, and machine learning (4Ms), and covers many length and time scales. Among our research areas of interest are: high-entropy alloys, nanomechanics, and laser metal additive manufacturing. 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, porous metals, quasicrystals, and metallic composites

· Mechanics: multiscale mechanics, in-situ instrumentation, and high strain-rate/temperature deformation

· Manufacturing: additive manufacturing (3D printing), cold spray technology, powder metallurgy, and micro- and nanofabrication

· Machine Learning: machine learning for materials/structure design and additive manufacturing
