Dr Rash completed his Honours (1996) and PhD (2001) on the pharmacological activity of spider venoms at the Department of Pharmacology, Monash University in the group of Professor Wayne Hodgson. After 18 months as an Assistant Lecturer at Monash Pharmacology, he was awarded an INSERM/NH&MRC Post-doctoral Fellowship to work in the group of Prof. Michel Lazdunski at the Institute of Molecular and Cellular Pharmacology in Antibes, France. It was here that he became involved in discovery and characterisation of venom peptides that act on acid-sensing ion channels, voltage-gated sodium channels and other pain related channels. Upon returning to Australia to the Institute for Molecular Bioscience (The University of Queensland), he established an ASIC research program and was awarded an NH&MRC project grant as CIA to investigate the molecular basis of the interaction of PcTx1 and APETx2 with ASIC1a and ASIC3 respectively. Dr Rash was appointed as senior lecturer in Pharmacology in the School of Biomedical Sciences in early 2016 where he continues his research on identifying novel bioactive peptides from animal venoms, unravelling the molecular basis for their specific channel interactions and their use as research tools and potential therapeutic lead molecules.
