About Raul

I am an Associate Professor of Human Nutrition and Physiology, with experience at institutions in Spain, Australia, and the United Kingdom. Currently, I teach various modules within the BSc (Hons) Dietetics, MDiet (Hons) Dietetics, MSc (Hons) Human Nutrition, and BSc (Hons) Nutrition, Exercise, and Health programs, among others, within the Faculty of Health.

For the past 20 years, my research has focused on the role of diet and physical exercise in nitric oxide metabolism and cardiovascular health. Recently, my interest has expanded to the oral microbiome, particularly the role of oral bacteria in enhancing nitric oxide bioavailability. I co-lead the Oral Microbiome Research Group alongside Dr Zoe Brookes at the University of Plymouth and am a member of the Dietetics, Human Nutrition, and Health Research Group. In addition to my research on human health, I am involved in global research on the nitrogen cycle, encompassing agricultural practices (fertilizers) and marine ecosystems (seaweeds). This work aims to address significant challenges, such as nitrate water pollution, while also promoting opportunities for the local economy in the South West of the UK.
