His interests include the molecular and cell biology of apicomplexan parasites, particularly Plasmodium and Toxoplasma, and aspects of this biology that may be targeted by chemotherapeutic interventions. Stuart is interested in understanding the essential housekeeping function of gene expression in these parasites and identifying how they differ from their animal hosts. His laboratory studies parasite gene transcription, post transcriptional regulation and protein translation, and characterises inhibitors of these processes. Dr Ralph joined the University of Melbourne in 2007 after postdoctoral research positions at the Pasteur Institute in Paris and the Walter and Eliza Hall Institute in Melbourne.
