One of the foremost Liver Disease and Nutrition researchers in the World, Nathan Davies is a Professor of Biochemistry at the UCL Faculty of Medical Sciences, #1 in London for Medicine and #10 in the world as a Faculty of Medical Sciences. Prof Davies is an expert in the field of Acute on Chronic Liver Disease. He has published over 135 peer reviewed publications and over 280 articles in total, has an outstanding H index of 43 and is currently an investigator on numerous research grants totalling over €15 million.

In addition to his ground-breaking work as a Liver Disease and Nutrition researcher, Nathan is both the Head of Education for the world leading Division of Medicine at UCL and the Director of Nutrition Education at UCL. Under Nathan’s leadership Nutrition has become one of the fastest growing areas of study at a Masters level in the entire UCL Medical Sciences Faculty. Nathan is also a registered nutritionist with The Association for Nutrition.


Nathan began his academic career at the University of Essex with a BSc Hons (II(i)) Biological and Medicinal Chemistry which was completed in 1994. He completed his PhD in Biological Chemistry also at the University of Essex in “Nitric Oxide in Sepsis” (1999). He has been a Visiting Senior Lecturer & Honorary Fellow at the University of Essex since 2001. He left the University of Essex to join UCL in 2001.


Prof Davies has appeared on a wide variety of major news programs, newspapers and websites. As one of the top liver disease and nutrition researchers in the world, he is often contacted by leading media to provide an expert view on a wide range of topics around nutrition.

Research Summary

As one of the world’s leading liver disease and nutrition researchers, Nathan’s new research is examining how your alcohol consumption and food choices determine the bacteria in your gut, effect the health of your liver and may even cause your liver to fail. If the liver stops functioning, this affects other organs and systems within the body.

As the liver is responsible for the general maintenance, supply of key nutrients and processing of waste, its inability to function places a considerable strain on the body. Typically, effects quickly become apparent in the kidneys, cardiovascular system and the brain.

In 2007 Prof Davies co-invented a new life-saving device that removes the toxins that accumulate in liver failure to prevent inflammation. This has the potential to allow the liver to regenerate. Nathan originally named the device “ARSENEL” after his favourite football team but it has been commercialised as “DIALIVE”. This invention was initially developed with funding from the NHS and the UK Medical Research Council, and is now in a Europe-wide clinical trial to test its efficacy.

The 24 patient ALIVER study commenced in July 2017 and has already saved its first patient. Full results will be available later in 2020.

He is currently listed as an inventor on 4 UCL patents, plus one shared Imperial College: UCL patent application. He has explored the commercialization of this IP as a stakeholder in the UCL spin-out company Yaqrit Ltd. Complementing this commercial interest, he became a member of the Ethical Review Panel in 2007 and was appointed Chair in 2017.

Teaching Summary

In addition to his roles as the Head of Education for the Division of Medicine at UCL and Director of Nutrition Education for UCL, Dr Davies is also the lead for 2 Masters Nutrition Courses and 1 Undergraduate Nutrition Degree.

Education - Undergraduate

In 2017, Nathan launched a unique Bachelor of Nutrition at UCL which integrates nutrition science with a rigorous foundational training in human biology and clinical medicine. 

This scientific nutrition course integrates the principles of biochemistry, physiology, pharmacology and basic anatomy with specialisms in sports nutrition, metabolism and studies of public health in both the developed and developing worlds.  

The holistic approach of the course ensures that students emerge with a broad range of skills and knowledge which allow them to adapt quickly to the fast pace of change in this growth industry. 

Education – Postgraduate

The MSc Clinical and Public Health Nutrition course provides a comprehensive overview of nutrition in modern clinical practice and the application of evidence based nutritional support across a range of communities. 

The program offers specialised training in the clinical and scientific basis of malnutrition and obesity, and therapeutic approaches to correcting this in the hospital, community and educational setting.

This Masters courses in Nutrition are ideal for those who wish to pursue a career in cutting-edge research or practice as health professionals.

The second program is the MSc Eating Disorders and Clinical Nutrition. This course on human nutrition is about practical approaches, research methods and nutrition in the general population and in disease states. Eating disorders are presented using different teaching methods with an extensive series of seminars, tutorials and brief clinical attachments at leading Eating Disorder services.
