Tel: 020 8240 2300


Yiannis is an associate professor and course lead of the MSc Nutrition and Genetics. He is also the head of the Nutrition and Genetics Research Group, which he created in 2015, and the research and enterprise lead for Allied Health and Life Sciences.

Career History

Yiannis is a registered dietitian (HCPC) and registered nutritionist (AfN). He completed an honours degree in Nutrition and Dietetics at the Robert Gordon University. He then did an MSc in Human Nutrition and Metabolism at the University of Aberdeen where he carried out research in DNA damage and nutrition.

He studied for his PhD at the Rowett Research Institute in the field of molecular nutrition where he investigated the effects of omega-3 fatty acids on cardiovascular disease through proteomics, genomics and metabolomics pathways. He did his postdoctoral research project at the University of Reading where he explored the sensorial quality and degradation of hospital food within the NHS.

Prior to coming to St Mary’s he was a lecturer at the London Metropolitan University, where he also completed a PGCert in Teaching and Learning in Higher Education. He is also a Fellow to the Higher Education Academy.

Yiannis has developed the pioneering MSc Nutrition and Genetics - the only university course of its kind in the UK, only four in the world.


Research profile

In his time at St Mary's University, Yiannis has developed and currently leads the Nutrition and Genetics Research Group. He supervises several MSc and PhD students and his main research interest is the interaction between genetics, nutrition, and chronic diseases (such as cancer, cardiovascular disease, diabetes, and obesity).
