Dr Karen Livesey is a theoretical condensed matter physicist based at the University of Newcastle and was a Scientific Associate Investigator in FLEET. Her research interests are in (i) exotic behaviours in magnetic thin films, and (ii) magnetic nanoparticles for biomedical applications. It is the first research area (magnetic thin films) that overlaps with the research themes within FLEET. Her current work is focussed on analytically calculating the size and shape of domain walls and skyrmions in order to provide scientists and engineers with simple tools with which to analyse experiments and design materials for important device application. Karen was a 2023-24 Superstars of STEM (Science and Technology Australia) and in 2023 toured the nation and gave 50 talks as the Women in Physics Lecturer (Australian Institute of Physics). She has featured in many radio interviews and public talks.
