Biography Summary

Guo-Xing Miao is an Associate Professor in the Electrical and Computer Engineering Department and is cross-appointed to the Institute for Quantum Computing at the University of Waterloo. Professor Miao's research interests lie in spintronics, which use precise electron spin manipulation for information processing. His work places a strong emphasis on nanodevices established on newly emerging spin platforms, such as synthetic diamonds and topological insulators, where information can be processed coherently on the quantum level, rather than digitally on the classical level.
