Biography

Dr. Guo-Xing Miao is an Associate Professor in the Department of Electrical and Computer Engineering and is affiliated with the Institute for Quantum Computing at the University of Waterloo.

Dr. Miao’s research focuses on spintronics, which involves the precise manipulation of electron spins for information processing. His work emphasizes the development of nanodevices based on emerging spin platforms, such as synthetic diamonds and topological insulators, where information is processed coherently at the quantum level, rather than using classical digital methods. He investigates the intertwined transport of electrons, spins, and ions in solid-state devices, aiming to advance semiconductor-compatible materials platforms for integration into chip technologies.
