My research interests are in fundamental quantum physics, with particular focus on superconductors and magnetic systems. My background also covers quantum error correction, entanglement, optimal state preservation, integrable systems and quantum optics. I received a joint honours degree in Physics with Philosophy from the University of York, U.K., where I was awarded the university's Goodwin Prize for Physics. I went on to do a Ph.D. at the University of Tasmania, Australia, under the guidance of Peter Jarvis, and then a postdoc at the Freiburg Institute for Advanced Studies, Germany. Since then I have been at NTNU and QuSpin, first as a postdoc with Jacob Linder and then as an independent researcher. In 2019, I won a grant from the Norwegian Research Council to establish my own group, and was awarded Outstanding Academic Fellow at NTNU. In 2025, the NRC awarded 12 MNOK for us to pursue the SuperFlex project, and I was awarded the Australian Institute of Physics Women in Physics Lecturer federal medal. My three children keep me busy the rest of the time, and I sometimes post on social media about work and life with the handle @SpintronicMum. (Photo: NTNU/Geir Mogen)
