James Cullen is a postdoctoral researcher in theoretical condensed-matter physics at the School of Physics, UNSW. He completed both his undergraduate degree (2019) and PhD (2025) at UNSW, focusing on quantum-mechanical approaches to transport phenomena in topological and spin-orbit-coupled materials. His research centres on spin and orbital based transport, including spin-orbit torques, charge-to-spin and charge-to-orbital conversion, and the role of Berry curvature and quantum geometry in electronic response. James aims to advance a fundamental understanding of how electrons, spins, and orbital degrees of freedom behave in complex materials, while contributing to the design of efficient pathways for information storage and manipulation.
