Associate Professor Jai N. Darvall holds dual appointments at the University of Melbourne in the Department of Critical Care, Melbourne Medical School, and the Department of Medical Education. He serves as an anaesthetist and intensive care specialist at the Royal Melbourne Hospital. Qualified with MBBS, MEpid, PhD, FANZCA, and FCICM, Darvall is a dual-trained anaesthetist and intensivist whose research centers on frailty in perioperative and critically ill patients, postoperative complications, and interventions in critical care. His work addresses key challenges such as frailty indexing from routine data, postoperative nausea and vomiting management, vasopressor administration timing in septic shock, and agitation during anaesthetic emergence in cardiac surgery patients.

Darvall has produced 94 research outputs with over 1,710 citations. Notable publications include 'Development of a Frailty Index from Routine Hospital Data' (Journal of the American Geriatrics Society, 2020), 'Frailty Indexes in Perioperative and Critical Care: A Systematic Review' (Anaesthesia, 2018), the protocol for the SNaPP randomised controlled trial investigating sugammadex versus neostigmine on postoperative pulmonary complications (2026), 'Chewing gum to treat postoperative nausea and emesis in female patients undergoing laparoscopic sterilisation' (BMJ Open, 2019), and 'Proceedings of an International Summit on Frailty in the Critically Ill' (CHEST Critical Care, 2026). As Principal Investigator of the Chewy Trial, a multi-centre randomised non-inferiority trial comparing chewing gum to ondansetron for postoperative nausea, he advances evidence-based perioperative care. Darvall received the 2017 ANZCA Melbourne Emerging Researcher Scholarship and Best Research Paper award from the Australian and New Zealand College of Anaesthetists, along with ANZCA project grants. In 2024, he was named an Emerging Leader mentee by the Australian Academy of Health and Medical Sciences, mentored by Professor Ian Davis. He supervises honours students in the Department of Critical Care and contributes to clinical ethics studies and research in extracorporeal membrane oxygenation.
