Dr Hawrelak is Head of Research at ProbioticAdvisor.com. His passion for gastrointestinal health, the GIT microbiota, and probiotics was ignited during the final year of his undergraduate training. Subsequently, Dr Hawrelak did his Honours (First Class) and PhD degrees in the areas of the gastrointestinal microbiota, irritable bowel syndrome, and the clinical applications of pre- and probiotics. He has written extensively in the medical literature on these topics – including 16 textbook chapters – and his research has been cited over 800 times. A list of some of Jason’s publications is below, with links to some of the articles.
Dr Hawrelak has taught health professionals at both the undergraduate and postgraduate level for the past 18 years. He currently coordinates and teaches the Evidence-based Complementary Medicine Program in the College of Health & Medicine at the University of Tasmania (Hobart, Australia) and is the Gastrointestinal Imbalances lecturer in the Master of Science in Human Nutrition and Functional Medicine program at the University of Western States (Portland, Oregon). He is also a Visiting Research Fellow at the Australian Research Centre for Complementary and Integrative Medicine (ARCCIM) at the University of Technology Sydney (Sydney, Australia).
He regularly presents to other health professionals at National and International conferences and has been a popular speaker for the Health Masters Live series – where he has presented his Gastrointestinal Masterclass series and lectures on Managing Paediatric Gastrointestinal Conditions and Building a Healthy Gut and Vaginal Dysbiosis. A number of his more recent presentations are detailed below.
Dr Hawrelak is on the Medical Nutrition Council of the American Society for Nutrition and in July 2015, Jason was awarded a Fellowship from the American College of Nutrition for his significant contributions to the teaching and practice of nutrition in Australia and North America.
His lectures and publications have changed the way thousands of practitioners in Australia, Canada, and the US manage gastrointestinal conditions and the microbiome – specifically their use of prebiotics and probiotics.
Dr Hawrelak is a clinician with more than 18 years’ experience working in busy natural medicine apothecaries and clinics. The main focus of his practice is in the treatment of gastrointestinal conditions, both acute and chronic – such as irritable bowel syndrome, ulcerative colitis, Crohn’s disease, gluten-related disorders, peptic ulcer disease, intestinal parasites, fructose intolerance, and SIBO.
