Senior Medical Scientist Dr Shifaza Mohamed prepares the Zirconium 89 tracer used in the project PD-L1 expression as a predictor of response to immunotherapy in mesothelioma. This is made possible by a generous donation from the Asbestos Diseases Society of Australia and funds associated with the 2021 Peter Thompson Award in Excellence, awarded to Dr Laurence Morandeau by the Charlies Foundation for Research.
