Dr Jalleh is an endocrinologist and early career clinician-scientist. He graduated (MBBS) from the University of Adelaide as the top graduate of his year, and was awarded the prestigious Everard Prize for the highest overall grade in medical school (2013), the University Medal (2014) for outstanding academic merit and the Top Scholar Award (2012) for outstanding performance in Obstetrics and Gynaecology. His PhD, focused on the relationship of gastric emptying with glucoregulatory responses and incretin physiology, conducted in the CRE in Translating Nutritional Science into Good Health, was highly productive with 17 publications in major subspecialty journals (first author in 15). His thesis was accepted in Jan 2024 and he was awarded both the Dean’s Commendation for Doctoral Thesis Excellence and the University Doctoral Research Medal from the University of Adelaide.

The theme of his research continues to be the relationships of gastric emptying with glucoregulatory responses and incretin physiology. He has presented his research at numerous international conferences including the European Association for the Study of Diabetes Meetings (EASD) in Barcelona (2019), Stockholm (2022) and Madrid (2024). He was a finalist in the Young Investigator’s Award at the Australasian Diabetes Congress in 2021 and was awarded a prestigious three-year Mary Overton Research Fellowship by the Royal Adelaide Hospital in Dec 2023. Dr Jalleh’s work has had a substantial impact on clinical practice and was recently cited in Australia’s consensus clinical practice recommendations (April 2025) endorsed by the Australian Diabetes Society (ADS), National Association of Clinical Obesity Services, Gastroenterological Society of Australia and Australian and New Zealand College of Anaesthetists regarding consumers taking GLP-1 receptor agonists. He continues ongoing collaborative work with esteemed international experts in gastric emptying and incretin physiology including Professor Michael Nauck, Professor Michael Camilleri and Professor Trygve Hausken.

Dr Jalleh has also been a strong advocate for research and is a member of the Australasian Diabetes Society Research Advisory Committee (since 2022). He has been working with the team to develop a National Diabetes Research Strategy. In addition, he has been part of the steering committee to organise the Adelaide Scientific Exchange Meeting 2024 to disseminate recent knowledge to fellow clinicians and is the convenor for the Adelaide Clinical Endocrine Society meetings. He has participated as a judge for the Australasian Diabetes Congress Quality in Diabetes Care Symposium in 2023 and 2024, and is now convening this initiative in 2025. He is regularly and increasingly invited to peer review journal articles regarding GLP-1 based therapies or incretin physiology and participates actively in this. This has included invitations to review by premier journals such as the Annals of Internal Medicine and The Lancet Diabetes and Endocrinology.

Dr Jalleh has been the primary recipient of prestigious research grants and awards including the NHMRC post-graduate scholarship ($132,743), Mary Overton Early Career Fellowship ($321,248) and ADS/RACP Research Establishment Fellowship ($50,000).
