Dr Athanasios Koutsos

  • Lecturer in Human Nutrition (Medicine)

Biography

Dr Athanasios Koutsos joined the School of Medicine, Dentistry & Nursing at the University of Glasgow in October 2021.

He holds a 5-year university degree in Food Science (2008) from the Aristotle University of Thessaloniki, Greece, and an MSc in Nutrition (2011) from the University of Reading, UK, funded by the prestigious Scholarship of the Greek State Foundation (IKY).

In 2017, he obtained his PhD from the University of Reading, UK, in collaboration with Fondazione Edmund Mach, Trentino, Italy, on a project exploring the effects of apple fibre and polyphenols on cardiovascular disease risk factors and gut microbiota. He then worked for four years as a Post-Doctoral Research Associate at the University of Reading on a BBSRC-funded project exploring the metabolic and gut-related mechanisms that underlie inter-individual variation in serum LDL-cholesterol in response to dietary saturated fatty acids.

Research interests

Dr Koutsos’s research focuses on the interplay between gut microbiota, health and disease. He investigates how diet, specific foods, as well as food components affect the composition and activity of gut microbiota to potentially manage or mitigate a spectrum of conditions, including cardiovascular, inflammatory, and metabolic diseases. To explore the complex interactions between diet, gut microbiota and health, he uses in vitro models of the human gut and dietary human intervention studies.
