Dr Raul Bescos Garcia

Lecturer in Dietetics (Physiology Specialist)

School of Health Professions (Faculty of Health)


My professional journey began as a research assistant at the High Performance Centre of Barcelona in 2004. I combined several roles in teaching and research within the higher education until I began a PhD in Exercise Physiology and Nutrition in 2008 at the University of Barcelona. I completed my PhD in 2012, and then I moved to Australia to work as a Postdoctoral Research Fellowship within the Institute of Sport, Exercise and Active Living (ISEAL, Victoria University, Melbourne) until I joined the University of Plymouth in November 2014 to take a post as a Lecturer in Nutritional Physiology.

Teaching interests

I teach undergraduate and postgraduate students on different aspects of physiology and nutrition. This relates to my interest in research on the impact of diet and exercise training regarding nitrate metabolism and cardiovascular health. 

Research interests

My current research focuses on the role of diet and physical exercise in shaping the oral microbiome with regards cardiovascular health. We are also investigating the effect of oral treatments for reshaping the composition and/or activity of the oral microbiome in order to enhance oral and cardiovascular protection.
