Dr Junjie Liu

Profile

Dr Liu joined Queen Mary University in 2024 as a lecturer in quantum technology. He completed his PhD in Physics at the University of Florida in 2012. During his PhD he investigated quantum tunnelling of magnetisation in molecular nanomagnets. His pioneering work included the first discovery of transverse anisotropy-induced slow relaxation of magnetization in these systems. Following his PhD, Dr. Liu moved to the University of Oxford as a post-doctoral researcher, where he worked on a wide spectrum of research topics including: coherent magneto-electric couplings, single-molecule electronic/spintronic devices and low-dimensional quantum magnets. In 2021 he was awarded a University Research Fellowship by the Royal Society. His fellowship aims to control and read out molecular quantum spins using electric fields instead of the more conventional magnetic field couplings.
