Steven Meikle is Professor of Medical Imaging Physics at the University of Sydney and Head of the Imaging Physics Laboratory at the Brain and Mind Centre. He is also the Research Academic Director (Research Infrastructure) in the Faculty of Medicine and Health.

Steven received his Ph.D. from the University of New South Wales in 1995. He was a medical physicist at Royal Prince Alfred Hospital in Sydney from 1987-2004, a visiting research associate at the Division of Nuclear Medicine and Biophysics, UCLA School of Medicine from 1991-2 and a post-doctoral research scientist at the MRC Cyclotron Unit in London from 1995-6, before joining the University of Sydney in 2004. His research aims to develop advanced PET, SPECT and related multi-modality imaging technologies that help elucidate the molecular mechanisms regulating brain function in health and disease. He was a founding Board member of the Australian Society for Molecular Imaging and is currently President of the IEEE Nuclear and Plasma Sciences Society. He is a Senior Member of the IEEE, a Fellow of the Australian Institute of Physics and serves on the Editorial Board of Physics in Medicine and Biology.
