Director, Clinical Toxicology Research Group, University of Newcastle

Dr 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 heads the Clinical Toxicology Research Group at the University. He has published over 240 original research publications and holds an NHMRC Senior Research Fellowship as well as being Chief Investigator on an NHMRC Program Grant and Centre for Research Excellence in Translational 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.

His first study of spider bite showed that the majority of spider bites cause minor effects, and the major effects only occurred with funnel-web spider bites and redback spider bites. The research also debunked the myth of the Whitetail Spider, showing that severe ulceration of the skin was due to a variety of causes but not spider bite. Other studies of bites and stings by venomous creatures, including scorpions, insects, marine animals and continues with snake bites in a national snake bite study formed the basis of his Doctor of Medicine titled: Data collection in clinical toxinology: debunking myths and developing diagnostic approaches to bites and stings
