Research description

Over the past three decades, we have seen a revolution in nanotechnology. Nanometer materials can be designed with unique properties that help us build faster computers, better cars, smarter sensors and more. Dr. Zhu seeks to better understand and design atomic and electronic structures consisting of nanoscale “imperfections” embedded within crystalline materials, such as functional oxides and lightweight alloys for advanced materials.

She and her research team are also investigating the formation dynamics and the performance characteristics of nanoscale features. Ultimately, the knowledge they acquire will be used to develop new methods of discovering, predicting and designing advanced materials with better mechanical, electrical or catalytic performance. These could have applications in the aerospace, automotive and energy industries.

Dr. Zhu received her B.Eng. in Materials Science and Engineering from Tsinghua University (Beijing, China) in 2007, and her M.Sc. and Ph.D. from McMaster University (Hamilton, Canada) in 2009 and 2012, respectively. After one year of post-doctoral research in Canada, she joined the faculty of Shanghai Jiao Tong University (Shanghai, China) as an Associate Research Professor in 2014 and was promoted to Research Professor in 2016. Since November 2017, she has been an assistant, and later associate, professor at the University of Manitoba, where she holds the Canada Research Chair in Mechanical and Functional Design of Nanostructured Materials.
