Who’s behind Gut Brain Science?

Doctors who have been working uniquely at the intersection between theoretical and applied microbiology and clinical practice for the treatment of gut-dysbiosis-related ailments — and a dedicated group of supporters, partners and others who have been drawn to the science and the clinical results.

The core team includes Medical Director, Dr Fi Lam, her practice management partner and a brand guardian and business strategy advisor — who work alongside participating Pharmacist, Mike Yang and co-creator, Gut Health Nutrition founder Karlene Georgiadis, who have both co-operated with Dr Lam for many years to help achieve positive patient outcomes. Her '9 Steps to Gut Greatness' give you a comprehensive guide to eating for gut wellness.

Microbiome testing is directed by Dr. Joshua Chou – a Harvard Medical School–trained academic and leader in regenerative medicine, biomedical technologies and translational innovation. Recognised as a Harvard Medical School Dean’s Scholar, he has built an international career spanning research, clinical translation, and advanced biotechnologies across the United States, Australia, and Japan. Dr. Chou integrates scientific rigour with practical healthcare solutions, focusing on AI-driven systems and next-generation therapeutic platforms.

Through Gut Brain Science, Dr. Chou brings his evidence-based, research-driven approach to microbiome testing. The platform is designed to deliver clinically meaningful insights into gut health and the gut–brain axis, combining advanced analytics with scientific precision to support personalised, data-informed health decisions.
