Professor Peter Leedman completed medicine at The University of Western Australia (UWA), then trained in endocrinology at Royal Melbourne Hospital in the mid-1980s. He completed his PhD at the Walter and Eliza Hall Institute in Melbourne with Len Harrison on autoimmune thyroid disease from 1987-1991. From 1991-1994 he was a Lucille P Markey Fellow with Bill Chin, a Howard Hughes Investigator in the Division of Genetics, Brigham and Women's hospital, Harvard Medical School in Boston where he worked on the molecular mechanisms of thyroid hormone action. He returned to Perth in 1994 as a Senior Lecturer in Medicine at UWA and became a Professor in 2003. Professor Leedman is an Endocrinologist, Head of the Laboratory for Cancer Medicine and Director of the Harry Perkins Institute of Medical Research.

Research overview
He has had a long-term interest in understanding how hormones act at the molecular level, with a focus on RNA biology and interactions between RNA and proteins, and how this information can be harnessed to personalise cancer therapy. His laboratory has focused on the mechanisms regulating expression of key therapeutic targets in hormone-dependent cancers (breast and prostate cancer) and more recently in poor prognostic tumors, including head and neck cancer and colon cancer. His team has identified key functional roles for a number of miRNAs in these tumors and uncovered several new members of a complex network of RNA-binding nuclear receptor hormone coregulators. His laboratory is focused on applying advances in understanding these molecular mechanisms to the development of novel therapeutics.
