The SAG was created in October 2014 to support the scientific and clinical development of the Company's compounds and brings together world renowned scientists with expertise in satiation, the human microbiome, and novel food ingredients.

Tim Spector is a Professor of Genetic Epidemiology at King's College London, Hon Consultant Physician at Guys and St Thomas's Hospital, London, and Director of the crowd funded British Gut project. He has published over 700 academic papers, leads the largest microbiome project in the UK, and is author of 'The Diet Myth: The Real Science Behind What We Eat'. The Diet Myth summarises scientific studies in an easy to read narrative into how gut bacteria affect our body weight and general health.

Tim's pioneering research into microbes, genetics and diet is regularly covered by radio, television and major national and international newspapers. Tim's research expertise in the microbiome creates opportunities to collaborate and additional insight into the role of the microbiome in health and disease.

About OptiBiotix Health PLC - www.optibiotix.com

OptiBiotix was formed in March 2012 to develop compounds which modify the human microbiome - the collective genome of the microbes in the body - to prevent and manage human disease.

The aim of OptiBiotix is to discover and develop microbial strains, compounds and formulations, which modulate the human microbiome and can be used as food ingredients and supplements or active compounds for the prevention and management of human metabolic diseases, examples of which include obesity, cholesterol and lipid distribution and diabetes.

OptiBiotix has established a pipeline of microbiome modulators that can impact on lipid and cholesterol management, energy harvest and appetite suppression. The development pipeline is fuelled by its proprietary OptiScreen® and OptiBiotic® platform technologies designed to identify metabolic pathways and compounds that impact on human physiology and bring potential health benefits. These platforms are applicable across a wider range of other human diseases.
