Biography

Associate Professor Leigh Johnston is a member of the Department of Biomedical Engineering within the School of Chemical and Biomedical Engineering. Her primary research focus is medical imaging, in particular Magnetic Resonance Imaging. Leigh holds an honorary appointment at the Florey Institute of Neuroscience and Mental Health, where she is Head of the Animal MRI facility. She is also a member of the Melbourne Brain Centre Imaging Unit, with research programs utilising the Siemens 7T and Siemens PET/CT clinical systems on the Parkville campus. Leigh’s expertise in MRI spans from acquisition sequences to image analysis and applications. Prior to her appointment at The University of Melbourne, Leigh was a postdoctoral researcher at the Howard Florey Institute (Melbourne), York University (Canada), and the Université catholique de Louvain (Belgium).
