Prof Geoffrey Isbister (BSc, MBBS, FACEM, MD, AM) Director, Senior Staff Specialist


Prof Geoffrey Isbister is a clinician researcher in clinical toxicology and his research has focused on understanding poisoning and envenoming in patients and undertaking studies to determine the effectiveness of antidotes and antivenoms in treatment of these conditions. He has published over 300 original research publications and is the Chief Investigator on an NHMRC Clinical Centre for Research Excellence in Venom and Antivenom Research. The benefits of the research include improving our understanding of the pathophysiology of both envenomation and poisoning. Much of his research challenges long held views about the treatment of poisoned and envenomed patients, including whether antivenom works. He has made clinicians re-look at what evidence there is for various treatments and why we use these treatments. He was awarded a Member of the Order of Australia in 2019 for his contribution to research in medical toxicology.
